Product Overview

The UCP 300 Series pillow block consists of a UC 300 Series bearing insert with a spherical outer diameter in a 2 bolt cast iron housing.

Bearing units consist of series of metric or imperial bore wide inner ring sealed ball bearings with spherical outer diameter inserted in a wide range of pressed steel and cast iron housings which are able to accommodate static misalignment.

Mounted bearing units are manufactured in a variety of bore sizes ranging from 12 -100mm or 1/2″ – 4″ with a variety of locking mechanisms and seals.

Special types for agricultural use are also manufactured.

Pressed steel housing styles cover a range of round and triangular flange units as well as pillow blocks.

More popular are the Cast Iron housing styles, which include long and short base pillow blocks, 2- and 4-bolt flange units, take-up units, flange cartridge units and hanger units.
