Bearings

• A bearing is a device to permit constrained relative motion between two parts, typically rotation or linear movement.

• Bearings may be classified broadly according to the motions they allow and according to their principle of operation. 

FUNCTION OF A BEARING:

• The main function of a rotating shaft is to transmit power from one end of the line to the other. 

• It needs a good support to ensure stability and frictionless rotation. The support for the shaft is known as “bearing”.

• The shaft has a “running fit” in a bearing. All bearing are provided some lubrication arrangement to reduced friction between shaft and bearing.

• Hold &Guide to shaft

• Smooth & Free motion to Save power
