Overview

Pillow Block Bearings

A pillow block bearing is a mounted bearing unit that supports a rotating shaft. It typically consists of an insert ball bearing fitted into a housing with a base that bolts to the machine frame. The shaft runs parallel to the mounting surface. Pillow block bearings are commonly used to support conveyor rollers, agricultural machinery and other industrial equipment.

Types of Pillow Block Bearings:

Pillow block bearing units can be grouped by how the bearing locks onto the shaft. Three common types are:
Set-screw pillow blocks (UCP): Screws in the bearing’s inner ring tighten against the shaft. This is a common design for conveyors and general industrial equipment.
Eccentric locking collar pillow blocks: A separate collar turns to grip the shaft and is secured with a set screw.
Adapter sleeve pillow blocks (UKP): An adapter sleeve fits between the cylindrical shaft and the tapered bore of the bearing. A locknut tightens the assembly onto the shaft.
Housing materials also vary by model. Cast iron is a common choice for general industrial use, while stainless steel or thermoplastic housings may suit applications that require greater corrosion resistance. When replacing a unit, check the full part number, shaft diameter, mounting dimensions and locking method. Series codes can vary by brand.

Pillow Block Bearing Applications:

Pillow block bearings are used on conveyor shafts, agricultural equipment, packaging machinery and other machines where a shaft needs support from a bolted base. In a conveyor, for example, pillow block units can support either end of a pulley shaft while allowing it to rotate.
Choose the housing material, seals and lubrication to suit the operating environment. A dry conveyor and a line that is regularly washed down can need different units. For food-processing equipment, confirm any requirements for washdown protection, corrosion resistance and food-grade lubricant before selecting a model.
