D21 Thrust Ball Bearing | D21 Thrust Bearing - 1-3/4" Bore

The D21 thrust bearing is a single direction, flat seat design thrust ball bearing with a 1-3/4" bore. What separates this bearing from some of the other D21 bearings on the market is its precision-made components, 52100 thru-hardened steel rings and balls, and high-quality, low-carbon steel band. This bearing is also supplied with light oil lubrication from the factory and features an oil hole in the band for relubricating. Thrust ball bearings are rotary bearings designed to support a predominately axial load. D21 bearings are composed of bearing balls that are supported in a ring and allow for use in applications with low thrust and little axial load.
