What is bearing which type of bearing

Question

Accepted Answer

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.

Bearings are used to support rotating shafts and reduce friction between two moving parts.
There are several types of bearings such as ball bearings, roller bearings, and plain bearings.
Ball bearings are the most common type of bearing and are used in applications such as electric motors and automotive wheels.
Roller bearings are used in heavy-duty applications such as conveyor belts and large motors.
Plain bearings are used in applications where there is no relative motion between the parts, such as in a piston engine.
Bearings are typically made of steel or ceramic materials.
Proper lubrication is important for the longevity and performance of bearings.
