Description
Fafnir Torrington RA100 RPB1 2-Bolt Pillow Block Ball Bearing Non-Expansion
The Fafnir RA100 RPB1 is a 2-bolt, non-expansion pillow block ball bearing unit manufactured by Fafnir, a brand of The Torrington Company (now part of Ingersoll Rand / Timken). It features a stamped steel zinc-plated housing in a classic saddle-style pillow block configuration with a set screw locking collar for shaft retention. The non-expansion design holds the bearing axially fixed in the housing, making it the locating or fixed-end bearing in a two-bearing shaft installation.

Applications
Pillow block bearings of this type are standard components in industrial shaft support applications across manufacturing, agriculture, HVAC, material handling, and general machinery. The 2-bolt pillow block configuration allows the bearing to be mounted to a flat surface or frame, supporting a rotating shaft at a fixed point. Non-expansion pillow blocks are used as the fixed (locating) bearing on a shaft where axial position must be controlled, typically paired with an expansion pillow block on the opposite end to accommodate thermal shaft growth. Fafnir pillow block units have been widely used in conveyors, fans, pumps, agricultural equipment, and light-to-medium duty industrial drives. Fafnir is a well-regarded American bearing brand with a long history of producing precision ball bearings for industrial use, originally founded in Hartford, Connecticut and later acquired by The Torrington Company.
