A four-piece precision spherical bearing with a .4375 in. bore and .9062 in. outer diameter, featuring a copper alloy insert and 4130 or 4340 alloy steel races, designed for metal-to-metal lubrication with a radial load capacity of 8625 lbs. and a weight of 0.05 lbs. The bearing has a ball diameter of .687 in., housing width of .437 in., and a hole chamfer of .032 in., with a tolerance of ±.015 in. across inserts.
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.
