3909 Thrust Ball Bearing | 3909 Thrust Bearing - 45mm

The 3909 thrust bearing is a single direction, thrust ball bearing with a 45mm bore and grooved races. What separates this bearing from some of the other 3909 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. 3909 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.
