The A 7Z 7-087 is a thrust bearing set comprising 10 hardened S.A.E 1018 steel balls held by a molded nylon retainer and two CR1075 steel washers, designed for axial load support in rotating applications. It has a bore diameter of 0.878 to 0.885 inch, an outer diameter of 1.365 to 1.374 inch, and a total thickness of 1.125 inch. The bearing supports a static load rating of 328 lbf at 100 rpm, with a maximum retainer temperature limit of 250°F. The components are rated for 15 rpm load capacity of 328 lbf and are assembled with retainer A 7M 7-087 and washer A 7Q 7-087.
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.
