Four-piece precision spherical bearing with a 0.3125 in. bore, 0.7500 in. outer diameter, and copper alloy insert, designed for metal-to-metal lubrication with a static radial load capacity of 5800 lbs. and a weight of 0.03 lbs. The housing has a 0.281 in. width, 0.562 in. ball diameter, and 0.419 in. ball flat diameter. The outer race is made of heat-treated 4130 or 4340 alloy steel with corrosion-resistant coating, and the ball is chrome-plated 52100 alloy steel.
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.
