  • 7. 7 Chapter - 1 PRESENT STATUS OF TECHNOLOGY1.1 INTRODUCTION The technology used is conventional type in unorganized sector. But theorganized sector players are using state of the Art Technology to manufacture thebearings as per the global standards. The unorganized sector players are alsogradually switching over to technology up gradation. The cluster units at Jaipur for bearing and Bearing componentmanufacturing units are employing conventional technology, but with the clusterlevel intervention the units have initiated technology. upgradation by employingCNC Machine for turning, grinding, finishing, testing, etc. The machining operation involved in manufacture of antifriction bearingsinclude 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 everymachine. Bearing permit smooth low friction rotary or linear movement betweentwo surfaces. It employs either a sliding or a rolling action. If we could reducefriction by only 10% in all the rolling bearing in use today, it would mean an energysaving equivalent to the combined out put of Not less than 25 large Nuclear PowerStations. Bearing can be broadly classified into two segments:- • Bimetal • Antifriction – BearingsBimetal bearings (also known as engine bearings) are primarily used in enginesof automobiles or machines. The bearings are meant to reduce the friction
  • 8. 8between the moving parts of the engine crankshaft or crank shaft or associatedsupport surfaces.Antifriction Bearings include Ball Bearings and Roller Bearings. Roller bearingscan further be subdivided into tapered roller. Cylindrical roller, Needle roller, thrustbearings and other special application bearings. The main components of anantifriction bearing are the inner race (ring), the other race (ring) the rollingelements, cages (retainers) and seals. The following are the major types ofbearing.a. Ball bearingb. Cylindrical roller bearingc. Taper roller bearingd. Needle roller bearingFurther 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 Duplex angular contact ball bearings Double row angular contact ball bearings Four point contact ball bearings Self aligning ball bearings Radial Ball Bearings Ball and Roller Bearings Ball Bearings Thrust Ball Bearings Roller Bearings Radial " Roller Bearings Thrust Roller Bearings

The unorganized sector includesthe small scale manufacturers and manufacturers of spurious bearings. Theunorganized sector contributes to about 18% of the total Industry turn over. Theunorganized sector players have a strong regional presence and mainly cater tothe needs of the replacement markets. The Indian bearing Industry is estimated atRs. 100 billion. The domestic Industry caters to the 74 % of total demand forcommon varieties & sizes. The organized sector units contribute around 53% ofthe Industry sales. The imports are about 26% of the total demand of the industry,
  • 10. 10while about 18% import comes through official channels. There is also estimated8% illegal imports. Legal imports generally represent the specialized / superprecision bearings not manufactured in India. Illegal imports generally representthe entry of spurious imports of bearings. The legal imports are about Rs.1 8.00billion while the spurious imports is about Rs. 8.00 billion. The small scale units manufacturing bearing are mainly concentrated inRajasthan and Gujarat having 15 and 50 units respectively. The bearingmanufacturing units are also present in Delhi, Punjab, and Maharastra. The stateof Rajasthan has major concentration of about 100 bearing componentsmanufacturing 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 manufacturingunits are the vendors of organized sector, and unorganized sector bearingmanufacturing units for supply of inner & outer races, balls, rollers, cages, seals,retainers & rivets. These components are also exported to Europe, United Statesof America and other global customers.There are about 450 to 500 number of spurious bearing assembling units situated in theState of Punjab, Delhi and Gujarat, eating the market of organized & unorganized sectorplayers. A number of global bearing manufacturers have established their units inIndia through joint ventures or 100% ownership and more are expected to followsuit.The Big player of bearing sector are present in U.S.A, Russia, Japan, Chinaand eastern Europe.

  • 28. 28Metal Shields - Bearing Metal Shields is protective closures which retains lubricants and assistin preventing contaminants from reaching internal surfaces. DustShields - The aperture usually found in the top cover housing is sealed to form a barrier toassist prevention of airborne contamination into the contact areaShielded Bearings - A shielded bearing has a metallic shield on the backside andShielded bearings are not sealed bearings. With the shielded type of bearing, grease mayenter the bearing readily, but dirt is restricted by the close fitting shields. If there is noshield on the backside of this bearing, the excess grease can escape into the innerbearing 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 iscarried out in compliance with total quality (self-inspection, SPC and TPM). Chapter-2 IDENTIFYING TECHNOLOGY GAP
  • 29. 29 The following section present on Analysis of Business operation for the Bearingand Bearing Component Cluster Jaipur. The following factors have been taken intoconsideration 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 IndianSupplier. • 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 thrustareas for development. Individual units have their own grading of quality. SKF, forexample, designates t, as Q77, Q66, Q55, where Q66 is reported as the prevalent leveland Q55 as the level aimed at International manufacturers are moving towards specialbearings, and sub assemblies involving bearings, where production of small batchquantities becomes more attractive.High rates and consistency of productivity have been achieved by the manufacturersabroad by line manufacture. The market demands there, permit mass productiontechniques 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 forcesbut usually from the collaborators insistence, if the latter has stakes, either financial orthrough its name.The following testing facilities are not available in most of the cluster units. • Chemical examination of steel. • Non Destructive Testing of Material. • MetallographicThe Machinery and equipment used by majority of SSI units for manufacturing of BearingRaces are of sub standard and obsolete. Even the SSI Bearing manufacturing units areusing the second Hand Imported Grinding & Honing Machine which are having LesserTolerance Accuracy so the bearing manufactured by these units are not preferred byInternational Industrial Buyer. The Product require high degree of precision the manufacturer are unable tomaintain Accuracy with in 2 microns. In accordance with the standard of InternationalMarket. The existing plant & machinery can give accuracy with 4 microns. The profile cutting operation of Bearing Races is not properly done due to NonAvailability of optical profile grinder.

The Quality of Bearing Races is concerned SSI Units have to follow the relevantspecification, drawing and other instruction provided by the purchaser. The system of100% inspection is being followed without any process wastage. However some of theBearing manufacturer permit 1% process wastage. In the event of rejection the unit hasto 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 100Micron) eccentricity in outer Dia and Track Dia or Base and Track Dia. The Radius formon 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 calibratedperiodically in order to ensure the quality of product. The most of SSI/Artisan Unit ofCluster do not have the well organized marketing channel and Demand forecastingsystem and are facing marketing problem due to lack of availability of sufficient fund andother resources required for Advertisement & Publicity, Credit required by the buyers,Branding, Market Assessment etc.Most of Artisan Units are having defective Product pricing system.

  • 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 ofBearing. The Problem of duplicating and Reconditioning of old Bearing are anotherConstraint in the Industry. SSI Bearing Manufacturing Units are also facing challenge from Indian LargeScale Bearing Manufacturer like SKF, NEI, TATA Bearing etc. as large scale unit havemade Huge Investment for Product Technologies, Collaboration from world leader ofBearing Industry. Large Scale units have employed the professionally qualified work forceand producing at higher volume as compared to SSI Units, and hence taken a lead in allthe functional Area of Manufacturing, R & D, Marketing etc. More over these units areusing latest and Innovative technique to have their higher productivity, quality andprofitability. The SSI Units are far away and yet to adopt these technique tool for theirbetterment 25 % of total demand for bearing industry is met by imports. While a part ofthe imports come through official channels, there is also a huge volume of illegal Imports generally represent the specialized bearings not manufactured in India.There are a large variants of imported bearings, each holding a small market share inIndia. Though, the quality of bearings manufactured by large players in India iscomparable to world standards, domestic manufacture is not viable due to the small sizeof the market segment. It becomes uneconomical to manufacture such type of bearings as it includes hugecapital expenditure. Illegal imports generally represent the entry of spurious imports ofbearings. In the past, the Indian bearings industry was highly protected on account ofvery high import duties ranging from 150% to 240% ad valorem. As a result, illegalimports via smuggling and under invoicing of imports was the order of the day, accountingfor a high 45-50% of total imports. While duty rates have come down over the last fewyears, a few countries like China, Russia, Eastern Europe dump their excess productionat a very low rate. This leads to a huge price differential between domestic and importedbearings (almost 40-50%), encouraging imports.• Most of the unit, the enterprise structure is proprietary or partnership type.

The automobile industry is the largest growth
  • 47. 47driver for OEM market as it accounts for almost 45% of total bearingmarket.Engineering sector, which accounts for 28% of total share, holds thesecond growth driver. Considering the high reliance of bearing industryon automobile sector, the fate of bearing industry is largely dependenton production of vehicles.The demand of bearing is also linked to heavy-duty industrialapplication in rolling stock, rolling mills, heavy earth movingequipments and other heavy machinery, accounting for 21% of totalbearing market. However demand in the latter category is met throughimports and therefore does not have significant impact on domesticgrowth .Up Swing in Automobile Sector ,The Indian Automobile sector hasgrown 16.5% in FY03 contributed by export growth of 65.3% anddomestic growth of 14.8%. The automobile industry comprising ofcommercial vehicles, passenger cars, multi-utility vehicles, two/threewheelers and tractors has performed extremely well in FY03. Thesharp growth of this sector has been partly driven by the impact oflower interest rate on demand, intermediated by a competitive financialsector, which has steadily cut prices of automobile loans as interestrates went down.Infrastructure has received a fillip in last 2 years through N-S-E-Wcorridor and Golden Quadrilateral projects. The transformation of roadtransport industry through these initiatives will lead to higher demandfor commercial vehicle industry. Passenger cars continue to grow indouble digit driven by rising aspiration levels and easy availability ofcheap finance. Within two wheelers, we expect motorcycle industrygrowth to continue on its growth path.After two bad years, the tractor industry is also likely to witness arevival with completion of inventory correction phase and goodmonsoons likely to drive demand. The positive outlook for auto sectoraugur well for bearings demand and we expect all segment ofautomobile industry to report strong growth in the coming year.Export PotentialExports of bearings companies has increased at a CAGR of 13% inlast seven years from 1995-96 to 2001-02 at Rs2.5bn.Big players inIndian ball and roller bearing have been already exporting a part oftheir production to developed countries like US, Europe etc. Domesticplayers are already sensing the outsourcing opportunity and haveinitiated the process of manufacturing a range of bearings for meetingthe requirements of global customers.The Indian bearing industry, especially the companies havingtechnical/ financial collaboration with global players like SKF Bearings,
