1. LUBRICATION SYSTEM PRESENTED BY:-VARSHA G. BANE T.Y.B.sc [AGRI] [

2. PURPOSE OF LUBRICATION  Reducing frication effect  Cooling effect  Sealing effect and  Cleaning effect

3. TYPES OF LUBRICANT  ANIMAL FAT = It does not stand much heat. It becomes waxy and gummy which is not very suitable for machine  VEGITABLE LUBRICANT = It is obtain from seed, fruit and plants and are used as lubricant in small simple machine EX. cotton oil, olive oil, castor oil etc EX. cotton oil, olive oil, castor oil etc  MINERAL LUBRICANT = It is most popular for engine and machine,obtained from Crude petroleum found in nature

4. PROPERTISE OF GOOD LUBRICATING OIL  It should have sufficient viscosity to keep the rubbing surface apart.  It should remain stable under changing temperature.  It should keep lubricated parts clean.  It should not corrode metallic surface
