The A 7Z 7M0717 is a metric thrust bearing set consisting of steel balls hardened to HRC 60 minimum, a molded nylon retainer rated for maximum 120°C, and a hardened steel washer. It has a bore diameter of 7 mm (tolerance 7.18 to 7.06 mm), an outer diameter of 17 mm (tolerance 16.97 to 16.79 mm), a ball circle diameter of 11.9 mm, and a bearing thickness of 1.57 mm with a tolerance of +0.06/-0.05 mm. The bearing contains nine balls with a diameter of 2.38 mm and has a static load rating of 605 N and a dynamic load rating of 320 N at 100 rpm. The retainer is made of molded nylon to accommodate operating temperatures up to 120°C.
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.
