Fafnir LRPB 1-3/16 Pillow Block Bearing 1-3/16" Bore Self-Locking Collar

Fafnir LRPB 1-3/16 Pillow Block Bearing 1-3/16" Bore Self-Locking Collar

The Fafnir LRPB 1-3/16 is an industrial duty pillow block housed bearing with a 1-3/16" bore and a self-locking collar for secure shaft retention. The unit combines a pre-greased ball bearing insert with a two-bolt zinc-plated steel housing, giving it a compact footprint that mounts flat to a surface and supports rotating shafts in a wide range of general industrial applications. Fafnir is a Torrington brand — one of the most recognized names in American anti-friction bearings.

Applications

Pillow block bearings like the Fafnir LRPB series are a standard component in industrial machinery wherever a rotating shaft needs support and alignment from a flat mounting surface. They are used in conveyor systems, fans and blowers, agricultural equipment, packaging machinery, pumps, and general power transmission setups. The self-locking collar design grips the shaft without requiring a keyway or set screw, simplifying installation and reducing shaft damage. The LRPB series is a light-duty to industrial-duty pressed-steel housing line, suited for moderate radial loads in non-harsh environments. Fafnir bearings have been manufactured in the United States since the early 1900s; the brand became part of Torrington and later Ingersoll Rand, and its bearing products remain widely used in maintenance and replacement applications across manufacturing and industrial settings.
