A 7Q 7-025 is a hardened CR1075 steel washer for use with the A 7Z 7-025 thrust bearing, which has a 0.253-0.258 inch bore, 0.555-0.562 inch outer diameter, and 0.406 inch thickness. The washer is designed for axial load applications and is used with a molded nylon retainer and S.A.E 1018 steel balls hardened to Rc 60 minimum. Load ratings for this bearing configuration are 131 lbf at 15 rpm and 69 lbf at 100 rpm. The washer dimensions and material comply with the bearing set specifications.
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.
