The A 7Z 7-100ST is a complete bearing set that includes a retainer with balls (A 7M 7-100ST) and two washers (A 7Y 7-100). The balls are made from 440C stainless steel, hardened to a Rockwell hardness of Rc 58-65, providing durability and resistance to wear. The retainer is constructed from molded nylon, suitable for temperatures up to 250¬8F, while the washers are made from 410 stainless steel, hardened to Rc 38-42. This bearing set is designed for various bore sizes ranging from 1/8 inch to 2-1/8 inches, with specific tolerances for each size. The load ratings vary depending on the bore size, with maximum ratings reaching up to 381 lbs at 100 rpm. The product is suitable for applications requiring low-friction rolling motion, enhancing the lifespan of rotating components by minimizing heat generation and energy consumption. Engineers should consider the A 7Z 7-100ST for projects that demand reliable performance in bearing applications, particularly where temperature and load conditions align with the specifications provided.
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.
