Extended inner ring ball bearings with a 0.125 inch bore and 0.3125 inch outside diameter, featuring a flanged design and double shields, are designed for low-friction rotation in precision applications. The part is made of 440C stainless steel and is lubricated with commercial grease. It has a dynamic load rating of 48 lbf and a static load rating of 17.6 lbf, with ABEC 3 precision. The bearing has a width of 0.1719 inch, an inner ring land diameter of 0.1406 inch, and an outer ring land diameter of 0.269 inch.
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.
