A 7Z 7-050ST is a stainless steel thrust bearing set for axial load applications, comprising a molded nylon retainer with eight 440C stainless steel balls and two 410 stainless steel washers. It has a bore diameter of 0.503 to 0.508 inch, an outer diameter of 0.930 to 0.937 inch, and a washer thickness of 0.71875 inch. The bearing supports a static load rating of 140 lb at 15 rpm and 74 lb at 100 rpm, with the retainer rated for maximum 250°F operation. The balls are hardened to Rc 58-65, and the washers to Rc 38-42.
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.
