The S99RH2MBNR1014 is a hardened and ground inner race designed for use with needle roller bearings on soft shafts, serving as a bearing bushing. It has a bore diameter of 10 mm and an outer diameter of 14 mm, with all corners chamfered for easy assembly. The part is made of alloy steel hardened to a minimum HRC 58, and its outer diameter is ground to a surface roughness of 0.40 µm AA. It is intended for use with a k6 shaft fit tolerance. Other sizes are available in the same series.
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.
