Applications

Ball pillow block bearings like the Fafnir RPB 3/4 are standard components used wherever a rotating shaft needs a fixed, bolt-down support point. Common applications include electric motors, pumps, conveyors, fans, agricultural machinery, machine tools, textile equipment, and general industrial drive systems. The stamped-steel housing keeps cost and weight low while the ball bearing insert handles both radial and light axial loads. Fafnir pillow block bearings have been widely used in North American industrial manufacturing for decades, and replacement units remain in demand for maintenance and repair of equipment still in service. The 3/4-inch bore size is one of the most common shaft sizes in light-to-medium duty machinery, making the RPB 3/4 a frequently needed maintenance part.
