PRESENT STATUS OF TECHNOLOGY
1.1 INTRODUCTION
The technology used is conventional type in unorganized sector. But the
organized sector players are using state of the Art Technology to manufacture the
bearings as per the global standards. The unorganized sector players are also
gradually switching over to technology up gradation.
The cluster units at Jaipur for bearing and Bearing component
manufacturing units are employing conventional technology, but with the cluster
level intervention the units have initiated technology. upgradation by employing
CNC Machine for turning, grinding, finishing, testing, etc.
The machining operation involved in manufacture of antifriction bearings
include forging of the rings, turning, heat-treatment, face and outer dia -grinding,
Bore and track grinding, finish and super finishing grinding , Demagnetizing,
cleaning, inspection assembly and packaging, etc.
The Product
The Bearing is a machine element used in rotating parts of virtually every
machine. Bearing permit smooth low friction rotary or linear movement between
two surfaces. It employs either a sliding or a rolling action. If we could reduce
friction by only 10% in all the rolling bearing in use today, it would mean an energy
saving equivalent to the combined out put of Not less than 25 large Nuclear Power
Stations. Bearing can be broadly classified into two segments:-
• Bimetal
• Antifriction – Bearings
Bimetal bearings (also known as engine bearings) are primarily used in engines
of automobiles or machines. The bearings are meant to reduce the friction

8. 8
between the moving parts of the engine crankshaft or crank shaft or associated
support surfaces.
Antifriction Bearings include Ball Bearings and Roller Bearings. Roller bearings
can further be subdivided into tapered roller. Cylindrical roller, Needle roller, thrust
bearings and other special application bearings. The main components of an
antifriction bearing are the inner race (ring), the other race (ring) the rolling
elements, cages (retainers) and seals. The following are the major types of
bearing.
a. Ball bearing
b. Cylindrical roller bearing
c. Taper roller bearing
d. Needle roller bearing
Further classification of these major categories is given below:
Single row deep groove ball bearings
Maximum capacity type ball bearings
Single row angular contact ball bearings

1.2 INDUSTRY OVERVIEW:
The bearing Industry in India can be divided into three segments; the
organized sector, comprising 12 leading manufacturers, located at Rajasthan,
Gujarat, Maharastra, Andhra Pradesh, Karnataka, Tamil Nadu, West Bengal and
Jharkhand primarily cater to the OEM Segment which are predominantly
automotive, Railway and other Industrial users. The unorganized sector includes
the small scale manufacturers and manufacturers of spurious bearings. The
unorganized sector contributes to about 18% of the total Industry turn over. The
unorganized sector players have a strong regional presence and mainly cater to
the needs of the replacement markets. The Indian bearing Industry is estimated at
Rs. 100 billion. The domestic Industry caters to the 74 % of total demand for
common varieties & sizes. The organized sector units contribute around 53% of
the Industry sales. The imports are about 26% of the total demand of the industry,

10. 10
while about 18% import comes through official channels. There is also estimated
8% illegal imports. Legal imports generally represent the specialized / super
precision bearings not manufactured in India. Illegal imports generally represent
the entry of spurious imports of bearings. The legal imports are about Rs.1 8.00
billion while the spurious imports is about Rs. 8.00 billion.
The small scale units manufacturing bearing are mainly concentrated in
Rajasthan and Gujarat having 15 and 50 units respectively. The bearing
manufacturing units are also present in Delhi, Punjab, and Maharastra. The state
of Rajasthan has major concentration of about 100 bearing components
manufacturing units with 1000 to 1200 Vendors carrying out turning job work.
There are substantial No. of component manufacturing units in Gujarat,
Maharastra, West Bengal and Punjab also. The bearing component manufacturing
units are the vendors of organized sector, and unorganized sector bearing
manufacturing units for supply of inner & outer races, balls, rollers, cages, seals,
retainers & rivets. These components are also exported to Europe, United States
of America and other global customers.
There are about 450 to 500 number of spurious bearing assembling units situated in the
State of Punjab, Delhi and Gujarat, eating the market of organized & unorganized sector
players.
A number of global bearing manufacturers have established their units in
India through joint ventures or 100% ownership and more are expected to follow
suit.The Big player of bearing sector are present in U.S.A, Russia, Japan, China
and eastern Europe. Some of leading bearing manufacturer are : -

1.7 Manufacturing Process
These are following three methods which are being used by units manufacturing
bearing races (Soft Turned).
BAR ROUTE :-
Bar route method is considered to be most economical method
manufacturing of soft turned Bearing Races. The following steps are involved in
this method. For the Inner Diameter upto 25mm , this method is more economical
as compared to the other method. That is why this method is more popular and it's
estimated that 70% of Bearing Races soft turning upto 25 mm I.D. size and 50%
Races of the total quantity of soft races manufactured by using this manufacturing
technology. Beyond 25mm I.D. this method is not much cost effective
Bar Turning
Drilling, Parting & Trepanning
(Trepanning is the operation in which the outer race & inner race is parted off from
a single piece of Bar).

Outer Dia Machining & Facing
Track and Radius Formation
Ready for dispatch for further operation
This process technology is preferably being used for the outer Dia of 25mm or
higher size. Apart 40% of the total volume of Soft Races turning is being produced
by using above mentioned method in the cluster.

23. 23
Forging Method:-
Bearing Races are manufactured by Hot Forging Method. The operation of Drilling,
parting, and trepanning are not required while using Forging Method. The Metallic
closed Dies are used in Hot Forging Method. This method is more suitable and
economical for outer Dia of 30 mm and above size. In the cluster Approx. 10% of
Bearing Races are produced by using Forging Method. The Forged Bearing Races
are machined/finished as Indicated in the earlier method.
Further Operation for Bearing Manufacturing

Metal Shields - Bearing Metal Shields is protective closures which retains lubricants and assist
in preventing contaminants from reaching internal surfaces.
Dust
Shields - The aperture usually found in the top cover housing is sealed to form a barrier to
assist prevention of airborne contamination into the contact area
Shielded Bearings - A shielded bearing has a metallic shield on the backside and
Shielded bearings are not sealed bearings. With the shielded type of bearing, grease may
enter the bearing readily, but dirt is restricted by the close fitting shields. If there is no
shield on the backside of this bearing, the excess grease can escape into the inner
bearing cap of the equipment bearing housing.
Assembly : Assembly of various items, performing additional functions (greasing,
marking, etc.) During each of these steps, the bearing manufacturing process layout is
carried out in compliance with total quality (self-inspection, SPC and TPM).

IDENTIFYING TECHNOLOGY GAP

29. 29
The following section present on Analysis of Business operation for the Bearing
and Bearing Component Cluster Jaipur. The following factors have been taken into
consideration in the Analysis.
• Raw Material
• Technology (Machinery & Production)
• Quality Standard
• Product & Marketing
• Entrepreneur & their Enterprises.
• Finance & working capital.
• Man Power Requirement
• Infrastructural Facilities.
• Business Development Service.
The raw material SAE 52100 Spherodised bearing steel only available from few Indian
Supplier.
• Indian Seamless Metal Tube, PUNE
• Indian Seamless Steel & Alloy, PUNE
• Mahindra Ugine Steel Company Khapoli.
Internationally, the accent is on achieving higher and higher quality levels of bearings.
Higher precision, minimum handling damages and maximum cleanliness are the thrust
areas for development. Individual units have their own grading of quality. SKF, for
example, designates t, as Q77, Q66, Q55, where Q66 is reported as the prevalent level
and Q55 as the level aimed at International manufacturers are moving towards special
bearings, and sub assemblies involving bearings, where production of small batch
quantities becomes more attractive.
High rates and consistency of productivity have been achieved by the manufacturers
abroad by line manufacture. The market demands there, permit mass production
techniques and thereby bring in economies in production.

30. 30
- As regards materials, closer grade and specification ratings are emphasised.
- Upgrading of technology has generally come not from within or from market forces
but usually from the collaborator's insistence, if the latter has stakes, either financial or
through its name.
The following testing facilities are not available in most of the cluster units.
• Chemical examination of steel.
• Non Destructive Testing of Material.
• Metallographic
The Machinery and equipment used by majority of SSI units for manufacturing of Bearing
Races are of sub standard and obsolete. Even the SSI Bearing manufacturing units are
using the second Hand Imported Grinding & Honing Machine which are having Lesser
Tolerance Accuracy so the bearing manufactured by these units are not preferred by
International Industrial Buyer.
The Product require high degree of precision the manufacturer are unable to
maintain Accuracy with in 2 microns. In accordance with the standard of International
Market. The existing plant & machinery can give accuracy with 4 microns.
The profile cutting operation of Bearing Races is not properly done due to Non
Availability of optical profile grinder.
Therefore lot of technological intervention need to be done in the area of
Machinery and Production in order to make final product as per International Standard.
The following observation need technological Intervention:-
(1). Use of Kerosene for Splash Cleaning for Assembled Bearing and Swab Cleaning
of Individual Parts.
(2). Inspection of Contamination level of the Bearing not inspected.
(3). Dust free Room/Assembly shop of Bearing not maintained.
(4) Erroneous measurement of parallelism, concentricity, flatness, taper, straightness,
radial and Axial clearance.
(5) Non Uniform Temp. in Shaker Hearth Furnace
(6) Mar Quenching Oil is being used for Quenching, but Mar Quenching Salt is not the
practice.

31. 31
(7) Blackening Salt is full of Contamination.
(8) Sampling System is Erroneous.
(9) Roundness Testing is used for setting parameter of M/c.
(10) Micro Structure Like Type of Martensite, Retained Austenite, Benetic Structure , is
not being inspected.
(11) Sub-Zero Treatment is not being done in the cluster
(12) Micro Hardness measurement is not practice .
(13) Speed, Feed and Depth of cut for Turning and grinding are not optimum .
(14) Precision Measuring Instrument are all shop made.
(15) Fatigue Testing of Bearing not being carried out.
(16) No phosphating of Inner and outer ring .
(17) Go-No-Go gauges practice is not existed.
(18) Forging Dies are made of H 11 & H13 Hot Die Steel and Hot H21 & H 23 material.
The Quality of Bearing Races is concerned SSI Units have to follow the relevant
specification, drawing and other instruction provided by the purchaser. The system of
100% inspection is being followed without any process wastage. However some of the
Bearing manufacturer permit 1% process wastage. In the event of rejection the unit has
to make payment for loss of the raw material the Bearing Manufacturer.
The main defects of Ball Bearing Races are Track Centre out (for which Unit is 100
Micron) eccentricity in outer Dia and Track Dia or Base and Track Dia. The Radius form
on Outer Dia and base of race is not proper which Account for major rejection.
The gauge calibration facility are not available as the gauge are required to be calibrated
periodically in order to ensure the quality of product. The most of SSI/Artisan Unit of
Cluster do not have the well organized marketing channel and Demand forecasting
system and are facing marketing problem due to lack of availability of sufficient fund and
other resources required for Advertisement & Publicity, Credit required by the buyers,
Branding, Market Assessment etc.
Most of Artisan Units are having defective Product pricing system. The units are cutting
prices due to cut throat competition.

32. 32
The Bearing Manufacturing SSI Units are only supplying to replacement market.
There is very vast scope to supply OEM & Other sector if they produce standard quality of
Bearing.
The Problem of duplicating and Reconditioning of old Bearing are another
Constraint in the Industry.
SSI Bearing Manufacturing Units are also facing challenge from Indian Large
Scale Bearing Manufacturer like SKF, NEI, TATA Bearing etc. as large scale unit have
made Huge Investment for Product Technologies, Collaboration from world leader of
Bearing Industry. Large Scale units have employed the professionally qualified work force
and producing at higher volume as compared to SSI Units, and hence taken a lead in all
the functional Area of Manufacturing, R & D, Marketing etc. More over these units are
using latest and Innovative technique to have their higher productivity, quality and
profitability. The SSI Units are far away and yet to adopt these technique tool for their
betterment 25 % of total demand for bearing industry is met by imports. While a part of
the imports come through official channels, there is also a huge volume of illegal imports.
legal Imports generally represent the specialized bearings not manufactured in India.
There are a large variants of imported bearings, each holding a small market share in
India. Though, the quality of bearings manufactured by large players in India is
comparable to world standards, domestic manufacture is not viable due to the small size
of the market segment.
It becomes uneconomical to manufacture such type of bearings as it includes huge
capital expenditure. Illegal imports generally represent the entry of spurious imports of
bearings. In the past, the Indian bearings industry was highly protected on account of
very high import duties ranging from 150% to 240% ad valorem. As a result, illegal
imports via smuggling and under invoicing of imports was the order of the day, accounting
for a high 45-50% of total imports. While duty rates have come down over the last few
years, a few countries like China, Russia, Eastern Europe dump their excess production
at a very low rate. This leads to a huge price differential between domestic and imported
bearings (almost 40-50%), encouraging imports.
• Most of the unit, the enterprise structure is proprietary or partnership type. The
proprietor/ partner himself look after the Management Aspect and Keep over all control of
the functioning of the unit and in most of the cases they do not posses the required
technical/Managerial back ground.

33. 33
• Technological Awareness of Entrepreneur are not upto the level. It need to be improved
so they can successfully compete the era of liberalization and globalization.
Finance is the most critical problem of the Industry in term of shortage of finance,
delayed payments, difficulties in getting bank finance and additional requirement of credit.
• Units require to maintain large inventory and it's the experience of manufacturer that the
working capital need are not fully realized by the bank & financial institution and it directly
affect their market.
• The SSI Units faces common problem regarding availability of skilled man power, A
worker After working for a period of few year in this Industry leave the Job to start his own
turning unit or to get higher wages from another unit.
• There is no regular training facilities available where the manufacturer and worker
undergo need based training.
• The SSI Units also faces problem about less availability of trained man power such as
turner, tool maker etc.
- The Tiny/Artisan Units are scattered in Different Area. They are functioning under
rented shop and due to availability of lack of space, the placement of machinery &
handling of material with in the unit is not proper.
- Due to frequent power cuts production is hampered.
- There is dearth of quality BDS in the Area of technology, Marketing, Export, Health
& Safety etc.
• Networking among R & D Centre, Technical Training Centre, Testing Centre are not
present in cluster.

PROPOSED ADVANCE TECHNOLOGY & ITS BENEFITS

39. 39
Bearing Steel :
The most common material used in the manufacture of bearing rings, balls
and rollers is Alloy steel conforming to specifications SAE 52100. This material has
become standard material for the industry all over the world. While the basic
material remains the same, the steel manufacturers all over the world have been
improving this material in order to improve the life span and quality of the bearing.
The Indian steel manufacturers although manufacturing steel to specifications SAE
52100, are not able to meet the requirement of the bearing manufacturers in so far
as purity and oxygen content is concerned. Therefore, bearing Steel
Manufacturers should be equipped with Vacuum Degassing & Vacuum Oxygen
De-Carburising Equipment (LEYBOLD HERAEUS, Germany.) In order to
maintain Oxygen content < 15ppm . The tubes are tested to ensure that the steel
is free from injurious imperfections such as piping, cracks, porosity, segregation or
injurious inclusions as referred to in ASTM-381.The inclusion rating is evaluated in
accordance with Plate III of ASTM E-45,The tubes are spheroidized and annealed
to ensure that the microstructure consists of spheroidized commentate in a ferrite
matrix with carbide size conforming to Plates 2 to 4 as per IS 4398-1972 and CG
2.1 - 2.3 as per SEP 1520-78.Spherodise annealing and normalising improves the
machinability of the annealed hypereutectoid steel and improves its microstructure.

Forged Bearing Races
1.0 INTRODUCTION : The profile envisage to set up Automatic Hot &
Cold Forming Forging Plant to manufacturer Bearing Races .The
operation of Drilling, parting, and trepanning are not required while
using Forging Method. The Metallic closed Dies are used in Hot
Forging Method. This method is more suitable and economical for
outer Dia of 30 mm and above size.. The Forged Bearing Races are
turned /finished on turning Lines.
2.0 MARKET & DEMAND ASPECT : The demand for bearing industry is
derived from demand in two key user segments - automobile and
industrial sector growth. The automobile industry is the largest growth

47. 47
driver for OEM market as it accounts for almost 45% of total bearing
market.
Engineering sector, which accounts for 28% of total share, holds the
second growth driver. Considering the high reliance of bearing industry
on automobile sector, the fate of bearing industry is largely dependent
on production of vehicles.
The demand of bearing is also linked to heavy-duty industrial
application in rolling stock, rolling mills, heavy earth moving
equipments and other heavy machinery, accounting for 21% of total
bearing market. However demand in the latter category is met through
imports and therefore does not have significant impact on domestic
growth .
Up Swing in Automobile Sector ,The Indian Automobile sector has
grown 16.5% in FY03 contributed by export growth of 65.3% and
domestic growth of 14.8%. The automobile industry comprising of
commercial vehicles, passenger cars, multi-utility vehicles, two/three
wheelers and tractors has performed extremely well in FY03. The
sharp growth of this sector has been partly driven by the impact of
lower interest rate on demand, intermediated by a competitive financial
sector, which has steadily cut prices of automobile loans as interest
rates went down.
Infrastructure has received a fillip in last 2 years through N-S-E-W
corridor and Golden Quadrilateral projects. The transformation of road
transport industry through these initiatives will lead to higher demand
for commercial vehicle industry. Passenger cars continue to grow in
double digit driven by rising aspiration levels and easy availability of
cheap finance. Within two wheelers, we expect motorcycle industry
growth to continue on its growth path.
After two bad years, the tractor industry is also likely to witness a
revival with completion of inventory correction phase and good
monsoons likely to drive demand. The positive outlook for auto sector
augur well for bearings demand and we expect all segment of
automobile industry to report strong growth in the coming year.
Export Potential
Exports of bearings companies has increased at a CAGR of 13% in
last seven years from 1995-96 to 2001-02 at Rs2.5bn.Big players in
Indian ball and roller bearing have been already exporting a part of
their production to developed countries like US, Europe etc. Domestic
players are already sensing the outsourcing opportunity and have
initiated the process of manufacturing a range of bearings for meeting
the requirements of global customers.
The Indian bearing industry, especially the companies having
technical/ financial collaboration with global players like SKF Bearings,

48. 48
FAG Bearings, Timken India, ABC Bearings and NRB Bearings are
expected to garner higher price in export market.
The OEM and replacement market control the market dynamics of
Bearing. The OEM and replacement market both account for 40% of
total demand of Bearing Industry individually. The Bearing
Manufacturer are only supplying to replacement market. There is vast
market of OEM Sector The SSI Bearing Manufacturing units of cluster
are mainly supplying to the replacement market of Bearing. On the
other hand a number of SSI Races Manufacturing Units are supplying
the Soft turned Bearing Races to the following large scale units. In the
Bearing & Bearing component manufacturers cluster Jaipur Approx.
10% of Bearing Races are produced by using Forging Method.

The Bearing Manufacturing SSI Units are only supplying to
replacement market. There is very vast scope to supply OEM & Other
sector if they produce standard quality of Bearing.
3.0 RAW MATERIALS : The raw material used in the Manufacturing of
bearing Races is SAE 52100 high Carbon Chrome bearing steel, which
has composition similar to EN-31 (100 CR 6 As per BIS specification).
The raw material for Bearing Races is in the form of Rods The Project
profile envisage to perform job work of large scale Bearing
manufacturers.
4.0 MANUFACTURING PROCESS & SOURCE OF TECHNOLOGY :
Manufacturing process begins by sending hot rolled bar material
through Induction Heaters to achieve the proper temperature needed
for forming the part. The material then proceeds into Hatebur 3 station
or 4 station hot former. Depending on the job specifications, these
machines pancake the part, then form and punch the inside diameter
through the product. Both machines possess the added feature of
combination forging, which produces two parts at the same time thus
reducing material waste.
At this point, depending on the application, the product can go
through forge normalizing or spheroidize annealing furnaces, cold ring
rolling process, shot blasting or visual inspection areas prior to the
shipping area.

4.1 Quality System :
The tests are conducted as per I.S. & A.S.T.M. standards. In the Laboratory, tests
such as Chemical Composition, Including rating, carbide Bending, Grain Size and
other tests are conducted. Once the material s approves after spherodized
Annealing, it is send for turning process where Inspection of pre-turned races is
done, continuous dimension inspection during turning process,100% Crack
Detection testing,100% Visual Inspection for dent, forging spots, rust & Burr of
turned races is done. After getting approval material is transferred for dispatch.
5.0 BASIS OF PROJECT SELECTION : The spurt in prices of the import
raw material-steel tubes, has compelled the industry to look for an
alternative form of material, which has been seen in forged/formed
rings.The proposed . Hatebur machines are impressive not only for
their precision and flexibility, but also because of their ability to
produce large volumes of parts at a high production rate which in turn
yields good production efficiency. In anticipating future demand &
keeping view of global trend only such a plant may be a approved
vendor of large scale bearing manufacturers.The proposed proven
technology has already adopted by M/S Agrasen Engineering
Industries Limited , Jaipur this technology , running very well , Hence it
justified the project selection.
6.0 PRESUMPTIONS: -
(1) To improve the energy efficiency of the plant, it has to run
continuously.
The scheme is based on two shift of 75% efficiency 25 days/month
and 300
days per annum
(ii) Labour wages has been taken as per market rate. It is likely to vary
depending upon the location of the project .
(iii) Rate of interest has been taken 12% on an average on fixed and
working capital. It is likely to vary due to financial outlay and the
location of the unit.
(iv) The operative period of the project is estimated to be about 8 years
considering technology obsolescence.
(v) Value of machinery & equipment is estimated on the basis
Quotations received & prevailing cost of the local mkt.
(vi) As the cost of raw Material is major part of working Capital and is
very high and as per the mrket trend the working capital is being taken
for 1.5 months only.
