An ABEC 3 extended inner ring ball bearing with a 0.25 inch bore and 0.50 inch outside diameter, featuring a double shield and lubricated with oil meeting MIL-PRF-6085. The bearing has a dynamic load rating of 114 lbf and a static load rating of 57 lbf, with dimensions including a width of 0.1875 inch, inner land diameter of 0.2188 inch, and outer land diameter of 0.1875 inch. The material is 440C stainless steel. The bearing is intended for applications requiring low-friction rotation and load support in industrial or mechanical systems.
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.
