The A 7Z56MBFM15MN is a flange-mounted self-aligning needle roller bearing with a 15 mm bore, designed for radial load support and angular misalignment up to ±5°. It features a drawn cup needle roller bearing and a carbon steel housing with black oxide finish, operating within a temperature range of -30°C to +100°C. The bearing requires a shaft material with HRC 58-64 hardness and a surface finish of 0.4 µm or finer. It has an overall length of 47 mm, flange height of 22.5 mm, and mounting hole diameter of 5.5 mm. The maximum rotational speed is 16,000 rpm, with a radial load capacity of 4800 N.
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.
