A 7M 7M2844ST is a thrust bearing set with a molded nylon retainer and hardened 440C stainless steel balls, designed for axial load support in rotating applications. The bearing has a 28 mm bore, a 44 mm outer diameter, a 36.5 mm washer thickness, and a total bearing thickness of 28 mm. It contains 12 balls with a diameter of 4.76 mm and has a dynamic load rating of 1566 N at 10 rpm and 832 N at 100 rpm. The retainer is rated for operation up to 120°C, and the washer is made of hardened 410 stainless steel. The bearing set operates with a maximum recommended speed of 900 rpm, where load capacity drops to approximately 50% of the 100 rpm rating.
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.
