The A 7M 7-037 is a thrust bearing component with a molded nylon retainer and hardened S.A.E 1018 steel balls, designed for axial load applications up to 175 lbf at 15 rpm and 93 lbf at 100 rpm, with a maximum retainer temperature of 250°F. The bearing has a 3/8 inch bore, a 13/16 inch outer diameter, and a bearing thickness of 19/32 inch. It is used with a CR1075 steel washer (A 7Q 7-037) as part of a complete thrust bearing set. The nylon retainer supports operation at speeds where load capacity degrades to approximately half at 900 rpm compared to 100 rpm.
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.
