Extended inner ring ball bearings with a 0.1875-inch bore and 0.3125-inch outside diameter, featuring a double shield and lubricated with Beacon 325 commercial grease, are designed for low-friction rotational support in precision applications. The part is made of 440C stainless steel, has an ABEC 3 tolerance grade, and is rated for a dynamic load of 76 lbf and a static load of 33 lbf. The bearing dimensions include a width of 0.1562 inches, an inner land diameter of 0.232 inches, and an outer land diameter of 0.329 inches.
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.
