The A 7Z56-BFM500N is a flange-mounted needle roller bearing with a 0.500 inch bore, designed for radial loads up to 950 lbf at a maximum speed of 22,000 rpm. It features a carbon steel housing with a black oxide finish and a drawn cup needle roller bearing. The bearing's overall length is 2.34 inches, overall width is 1.78 inches, mounting hole distance is 1.53 inches, and flange thickness is 0.77 inch. It supports shafts with a hardness of Rc 58 to 64 and a surface finish of 16 µin. or finer. Operating temperature ranges from -22°F to +212°F, and the flange allows self-alignment up to ±5°.
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.
