A two-piece precision spherical bearing with a 0.7500 in. bore and 1.4375 in. outside diameter, made of 4130 or 4340 alloy steel outer race and 52100 alloy steel ball, heat-treated and chrome-plated for corrosion resistance. It has a static radial load rating of 78,000 lbs, a total width of 0.750 in., and includes a lubrication hole and groove. The bearing is designed for metal-to-metal contact with a chamfer of 0.015 ± 0.000 in. and an inner ball flat of 0.020 in.
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.
