What are the anti friction bearings?

Antifriction bearing which is also recognized as rolling contact bearing is used to provide a low friction surface. It is used when little friction is required on rotating or sliding surfaces. These bearings are made up of races and elements. There are many benefits of using these bearings as they minimize the requirement of lubrication and also decrease starting and operating friction. As the friction is less, it requires less power to rotate the engine components and as a result, the output of the engine increases.

There are two types of anti-friction bearing

• Axial ball
• Roller bearing
