A 7Z 7M2541ST is a stainless steel thrust bearing set comprising 440C stainless steel balls hardened to HRC 58-65, a molded nylon retainer rated for 120°C maximum, and a 410 stainless steel washer hardened to HRC 38-42. The bearing has a bore diameter of 25 mm (tolerance 25.30-25.07 mm), an outer diameter of 41 mm (tolerance 40.97-40.69 mm), and a total thickness of 33.3 mm. It contains 10 balls, each with a diameter of 4.76 mm, and has a static load rating of 1428 N at 15 rpm and 756 N at 100 rpm. Load capacity at 900 rpm is 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.
