The A 7Z 7-037 is a thrust bearing set consisting of six hardened S.A.E 1018 steel balls, a molded nylon retainer rated for up to 250°F, and two CR1075 steel washers hardened to Rc 59-61. It has a bore diameter of 3/8 inch, an outer diameter of 13/16 inch, and a total thickness of 19/32 inch. The bearing supports a static load rating of 175 lbf at 15 rpm and 93 lbf at 100 rpm. The retainer and washer components are available separately as A 7M 7-037 and A 7Q 7-037 respectively.
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.
