Overview
The Dodge P2B-SC-108 pillow block bearing is a standard-duty, mounted ball bearing unit designed for straightforward shaft support and alignment in general-purpose machinery. This non-expansion, two-bolt pillow block features a 1-1/2″ bore with a 208-series ball bearing, precision-hardened and honed for reliable performance. The set screw locking mechanism and cast iron housing make it a proven choice for conveyors, mechanical drives, and moderate-duty power transmission systems.
