A 7Z48-FSN500 is a nonaligning self-clinching needle roller pressbearing with a 0.5 in bore, designed for high-speed, high-load applications. It features knurling for secure installation in a 0.875 in panel hole with a 0.06 in thickness, and requires a shaft diameter between 0.4995 in and 0.5000 in. The bearing has a maximum radial load capacity of 950 lbf and operates at speeds up to 22,000 rpm. It is constructed with a drawn cup needle roller and carbon steel housing with a black oxide finish, and functions within a temperature range of -22°F to +212°F.
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.
