BNDIRXM1215225 is an alloy steel inner race for needle bearings, designed for press-fit installation on soft shafts and usable as a hardened bushing, with a bore of 12 mm, an outer diameter of 15.001 mm, and a width of 22.5 mm. The inner race is hardened to HRC 58 minimum, features an O.D. ground to 0.4 µm AA surface roughness, and has all corners chamfered for easy assembly. It conforms to H6 tolerance for bore, h5 for outer diameter, and h6 for width per the metric tolerance chart for dimensions between 10 and 18 mm. The part is intended for applications requiring shaft translation support.
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.
