Plummer Block and Pillow Block Bearing Units

At Uni-Drive, we supply a comprehensive range of Plummer Block and Pillow Block Bearing Units engineered for reliable performance in demanding industrial environments. Designed to support rotating shafts with high load capacities, these housings offer excellent alignment, stability, and protection for the bearing insert. The rigid cast-iron or ductile-iron construction ensures durability even under heavy mechanical and thermal stresses, making them ideal for applications in fans, conveyors, pumps, and process machinery.

Each housing is designed for easy installation, alignment, and maintenance, reducing downtime while improving operational efficiency. The integrated sealing system provides effective protection against dust, moisture, and contaminants, ensuring long service life and consistent performance even in harsh environments. Various housing designs and sealing arrangements are available to suit standard and custom shaft configurations.

Uni-Drive Plummer and Pillow Block Bearings are available for shaft diameters ranging from light to heavy-duty series. They can accommodate different locking methods—such as adapter sleeves, eccentric locking collars, or set-screw fastening—and can be supplied with relubrication options for extended maintenance intervals. Whether for general machinery, HVAC systems, or high-speed industrial drives, Uni-Drive bearing housings deliver dependable performance and long-term value for every application.
