A 7Q 7-112 is a hardened CR1075 steel washer used as a component in the A 7Z 7-112 thrust bearing set, with a thickness of 0.125 inches and an outer diameter tolerance of ±0.005 inches. It is designed for use with a nylon retainer and 12 S.A.E 1018 steel balls hardened to Rc 60 minimum, supporting a load rating of 267 lbf at 100 rpm. The washer is specified for applications with a maximum retainer temperature of 250°F.
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.
