PRINCIPAL OF BEARING

PRINCIPAL OF BEARING

Rolling bearings usually consists of the outer ring, inner ring and rolling element and cage composed of four main parts. A small number of structures without inner ring or no outer ring or no rings, consists of three parts or other parts. Rings or washers, duty cycle and the outer ring, thrust bearing is close to the ring and living area.Ball bearing inner and outer rings of cylindrical surface in a round face on the Raceway (Groove) Guide pulley, limit rolling side movement, but also to increase the rolling elements and the circle of contacts, reduce exposure to stress. Rolling is guaranteed between the bearing inner and outer rings with rolling friction parts, its shape, size and number of direct influence on the rolling bearing load capacity and performance.

 To understand the bearing see friction in metal part

Bearing reduce friction between two moving parts with the hep of rolling element .The material of rearing used.Bearing may be axial but to study the bearing we first discuss the rolling fixture.


ROLLING FRICTION

 To moving parts always offer friction & bearing always provide the smooth rolling action between them.
