The A 7Q 7-012 is a hardened CR1075 steel washer, 0.050 inch thick, for use with thrust bearing assemblies featuring S.A.E 1018 steel balls and a molded nylon retainer. The washer has an outer diameter tolerance of 0.430 to 0.437 inch and is designed for applications with maximum operating temperatures of 250°F. It is specified as a component for the complete thrust bearing set A 7Z 7-012, which includes six balls and operates at rated loads of 63 lbf at 100 rpm and 31.5 lbf at 900 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.
