The A 7Q 7M0717 is a hardened carbon steel washer for use in thrust bearing assemblies, with a thickness of 1.27 mm and an outer diameter tolerance of 16.97 to 16.79 mm. It is designed to work with a 7 mm bore and pairs with a molded nylon retainer and S.A.E 1018 steel balls hardened to HRC 60 min. The washer is made of CR1075 steel hardened to HRC 59-61. The complete bearing set supports load ratings of 320 N at 100 rpm and 160 N at 900 rpm, based on the series data for A 7Z 7M0717.
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.
