Bearings

Bearings Bearing refers to any kind of support in direct contact with a moving machine parts. Most of the bearing supports the rotating shafts or spindle. Mainly they are used to minimize the friction, wear and power loss. Types of bearings: 1.       Plain or sleeve bearing 2.       Antifriction bearing Plain bearing:             Plain bearing is a simple cylindrical shape where shaft rotates through the journal area by the separation of a film of lubricating oil. Antifriction bearing:             The bearing where various rolling element like steel balls, rollers etc is used called antifriction bearing.                                                                     Figure: Antifriction bearings (rollers and balls). Bearing selection: Bearing selection depends upon the factors – Ø   Power consumption Ø   Working life time Ø   Types of load caring (axial or radial) Ø   Tolerance and fitness Ø   Shaft speed (rpm) Ø   Ope
