Definition of Bearing 

A bearing is the machine element which support another moving machine element (shaft). It permits the relative motion B/W the contact surfaces while carrying the load.

Classification of Bearing

1)Depending upon the direction of load to be support

a)Radial Bearing
b)Thrust Bearing

 2)Depending upon nature of contact

a)sliding contact bearing
b)Rolling contact bearing

Types of Bearing 

Bearing can be categorized into two main types

1)Plain bearing(sliding contact)
2)Anti friction bearing(Rolling contact)

1)Sliding contact

a)Radial bearing
b)Thrust bearing
c)Guide bearing

2)Anti friction or Rolling contact Bearing

a)Ball bearing
b)Roller Bearing

Ball bearing

a)Deep groove ball bearing
b)Self aligning ball bearing
c)Angular contact ball bearing
d)Four point contact ball bearing

Roller bearing

a)Cylindrical roller bearing
b)Needle roller bearing
c)Spherical roller bearing
d)Tapered roller bearing
