A 7M 7-125 is a nylon retainer with hardened S.A.E 1018 steel balls for use in thrust bearings, designed to maintain ball spacing and reduce friction in rotating assemblies. It is compatible with the A 7Z 7-125 complete thrust bearing set, which has a 1-1/4 inch bore, 1-7/8 inch outer diameter, and 1-9/16 inch washer thickness. This component supports a static load rating of 545 lbf at 100 rpm and operates at temperatures up to 250°F. The bearing set includes a CR1075 steel washer hardened to Rc 59-61 and 14 balls with a tolerance of ± .0001 inch.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
