A 7M 7M0512ST is a thrust bearing retainer component designed for use with 440C stainless steel balls and a 410 stainless steel washer in a complete bearing set. It is part of a metric series with a bore diameter of 5 mm (tolerance: 5.21...5.08 mm) and an outer diameter of 12 mm (tolerance: 11.96...11.78 mm). The retainer is molded from nylon rated for maximum temperatures of 120°C. The complete bearing set includes seven balls of 3.18 mm diameter and has a load rating of 391 N at 15 rpm and 218 N at 100 rpm.
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.
