UCP Series Pillow Block Ball Bearings

This is the most typical ball bearing unit, designed with a rib in the center of the base for maximum strength and minimum deformation. The UCP209 series consists of a two-bolt cast iron housing (standard P209) in which an outer spherical ball bearing (UC209) with set screw locking is installed. These bearings usually contain a grease nipple (grease fitting) for relubrication and possibly an anti-rotation pin or anti-rotation collar.

Function and Maintenance of Pillow Block Ball Bearings

The set screw locking on the extended inner ring ensures a secure connection to the shaft. Relubricable inserts are added via grease nipples. Self-aligning capability due to the convex/concave geometry. Some variations include triple lip seals (L3), anti-rotation pins and collars
