Fafnir RPB 5/8 Pillow Block Ball Bearing Two-Bolt Light Duty Torrington 5/8"

The Fafnir RPB 5/8 is a light duty, two-bolt pillow block ball bearing manufactured by Fafnir, a brand of The Torrington Company. It mounts a standard ball bearing in a stamped steel housing with two bolt holes, allowing the bearing to support a rotating shaft at a fixed point on a frame or surface. The 5/8" bore accepts a 5/8-inch diameter shaft, secured by a setscrew locking collar.

Applications

Pillow block ball bearings are a standard mounting solution in industrial and light machinery wherever a shaft needs radial support at a fixed mounting point. The two-bolt base style mounts flat against a surface — typically a machine frame, conveyor structure, or equipment chassis — with two bolts through the base flanges. The RPB series from Fafnir is a light duty pressed-steel housing designed for lower-load applications such as small conveyors, agricultural equipment, fans, and general light industrial machinery. Fafnir is a well-established American bearing brand, produced under The Torrington Company, and these bearings have been widely used in U.S. manufacturing and industrial maintenance for decades. The setscrew locking collar fixes the shaft axially within the housing and allows for straightforward installation and removal. These units remain in active use today for replacement and maintenance of existing machinery as well as new light-duty fabrication projects.
