In addition to industrial applications, lubricants are used for many
other purposes. Other uses include cooking (oils and fats in use
in frying pans, in baking to prevent food sticking), bio-applications
on humans (e.g. lubricants for artificial joints), ultrasound
examination, medical examination. It is mainly used to reduce
friction and to contribute to a better and efficient functioning of a
mechanism.
A lubricant is a substance, usually organic, introduced to
reduce friction between surfaces in mutual contact, which
ultimately reduces the heat generated when the surfaces move. It
may also have the function of transmitting forces, transporting
foreign particles, or heating or cooling the surfaces. The property
of reducing friction is known as lubricity.

 Reduction of wear & tear Reduces m/c maintenance time & cost.
 Synchronized m/c operation appropriate rpm of m/c in optimal speed &
uniformity of speed.
 Legibility assurance of m/c & m/c parts.
 Higher operating efficiency less idle time & stopping.
 Better quality of products: due to well-running & disturbance are the causes of
better quality products. Reduces m/c stoppage frequency, so attainment of the
higher quality.
 Reduces fatigue & boredom of work forces due to well running less stoppage &
troubles.
 Develop ergonomics & improve working environment.
 Above all maintenance, reduce work load & cost of overall manufacturing.

 Viscosity
 Sp. gravity
 Flash point
 Pour point
 CST(Centistroke)
 Volatility
 Acid no of parts per million (ppm)
CHARACTERISTICS of LUBRICANT

6. 7/15/2020Slide Prepared by- Md. Shamsuzzaman 6 of 14
Selection of lubricant is governed by following factors
 Types of gear/bearing or point of lubricants
 Speed of gears/shaft (in case of seal box of gear)
 Reduction ratio
 Operating temperature
 Input horse power
 Nature of load provided
SELECTION of LUBRICANT

7. 7/15/2020Slide Prepared by- Md. Shamsuzzaman 7 of 14
Outcome from the physical properties
 Lubricant must be resist oxidation
 Lubricant must be resist carbon formation
 Lubricant must be resist rust formation
 Lubricant must anti-foaming
 Lubricant must be resist extreme load
 Lubricant must possess required viscosity
 Lubricant must act goods cleaning agent (CCl4, petrol, diesel)
FUNCTIONAL PROPERTIES of LUBRICANT

Spinning machines: excellent corrosion protection for bearings, spinning
turbines, opening rollers, spinning pumps, and spinnerets
Knitting machines: long service life with minimum maintenance requirements
for needles and sinkers, slide rails and guide bars
Weaving machines: longer intervals between maintenance operations due to
minimum-quantity lubrication for gears, gripper looms and chains
Finishing machines: resistance to water, steam, acidic and alkaline solutions for
steamers, rolling bearings, compensators and rollers
Stenter frames: less residue due to high separating effect on conveyor chains,
adjustment spindles, needle bars and clips
Where are lubricants is use in the textile industry?

Increasing productivity by 150% with lubricants
 a considerably lower consumption of natural resources
 efficient and reduced amount of material used
 less waste
 increased occupational safety due to lower lubricant consumption
 higher cost effectiveness for the operator

Thermal/ temperature stability: If oil becomes hot in use, then it is important
that it should not make it break down so that it ceases to lubricate properly.
Speed: Higher the speed of moving parts, lower should be the viscosity of the
lubricant.
Load: Higher the load to be carried, higher should be the viscosity of the
lubricant.
Heat conductivity: When the lubricant is used with bearing & other moving
parts, it should be able to carry away heat generated.
Flammability: This is the very important factor while selecting a type of
lubricant. The lubricant or oil selected should not be able to catch flame. For
example, it is most important in aviation, coal mining etc.
Factors Considered For Lubricant Selection

11. 7/15/2020Slide Prepared by- Md. Shamsuzzaman 11 of 14
 Storing of too many lubricant types should be avoided.
 The specific quantity of each type of lubricant should be stored in the specific
size of containers.
 Lubricant storage is often combined with solvent & paints. The overall fire risk
is high & storage should be in the separate building with fire precautions.
 Smoking & naked flames should always be banned in lubricant storing area.
 Access to lubricant stores should be restricted to very few people authorized to
issue & dispense lubricant.
 The large storage tank of rectangular shape should be placed few inches above
the ground, to avoid corrosion of the base. Standard distance is 3 ft.
 Drums have to be stored vertically & pump is used to dispense oil.
 For taking grease from container wooden spoon should be used.
 The tray can be used to store excessive oil & can be reused.
 A cover should be always clean before opening, otherwise, it will contaminate
lubricant & affect its properties.
