A 7M 7M1224ST is a thrust bearing set consisting of a molded nylon retainer with 440C stainless steel balls and a 410 stainless steel washer, designed for axial load support in rotating applications. The bearing has a bore diameter of 12 mm with a tolerance of 12.19 to 12.06 mm, an outer diameter of 24 mm with a tolerance of 23.98 to 23.80 mm, a washer thickness of 1.27 mm, and a total bearing thickness of 18.3 mm. It supports a dynamic load rating of 623 N at 15 rpm and 329 N at 100 rpm. The retainer is rated for maximum operating temperature of 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.
