Lubrication for Bearings

Bearing lubrication is?vital for preserving the performance and lifespan of rolling element bearings. Lubrication helps separate moving parts relative to one another, such as rollers and raceways or balls, to prevent wear and tear and friction.

Lubrication is one of the most important factors determining bearing performance. The suitability of the lubricant and lubrication method have a dominant influence on bearing life.

Functions of lubrication :

• To lubricate each part of the bearing, and to reduce friction and wear
• To carry away heat generated inside bearing due to friction and other causes
• To cover rolling contact surface with the proper oil film in order to prolong bearing fatigue life
• To prevent corrosion and contamination by dirt
