Bearings Structure, Classification & Features

Structure of a Bearing

A common bearing is composed of a ball or a roller, a retainer, rings (inner ring and outer ring), lubricants

and seals (selectable).

Classification of Bearings

There are several types of bearing which are classified according to the shapes of their rollers. Generally,

there are ball bearing, roller bearing and a combination of the two.

Features of Bearings

A ball bearing has the characteristic of low friction. It is suitable for applications which demand high speed,

high precision, low torque and low vibration. Whereas a roller bearing has a large capacity for load so it is

suitable for applications which demand high load, shock load and longer bearing life.
