A 7M 7M0717 is a thrust bearing retainer and ball assembly for use with a washer, forming a complete thrust bearing set with a 7 mm bore, 17 mm outside diameter, and 11.9 mm bearing thickness. The balls are made of S.A.E. 1018 steel hardened to HRC 60 minimum, and the retainer is molded nylon rated for maximum 120°C operation. The bearing supports a dynamic load rating of 605 N at 15 rpm and 320 N at 100 rpm, with eight steel balls of 2.38 mm diameter. The washer is made of CR1075 steel hardened to HRC 59-61.
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.
