UCP311 Pillow Block Bearings

UCP311 Pillow Block Bearing | 55mm Bore Heavy Duty Bearing Unit

The UCP311 pillow block bearing is a heavy-duty integrated mounted bearing unit with a 55mm bore. Designed with a thickened housing and reinforced structure, it provides higher load capacity and rigidity than standard UCP2 series bearings. It features self-aligning capability and dual set screw locking, ensuring stable rotation, fast installation and reliable performance for heavy-duty industrial power transmission.

Product Material

Bearing Core: Manufactured from high-grade GCr15 bearing steel with professional heat treatment. It offers high hardness, excellent wear resistance and pressure resistance, supporting long-term stable heavy-load continuous operation.

Bearing Housing: Built with thickened high-strength cast iron. It delivers superior shock resistance and vibration stability, suitable for harsh and high-intensity industrial working environments.

Core Features

Reinforced heavy-duty structure delivers higher load capacity than regular bearing units. Built-in self-aligning design compensates for shaft misalignment and mounting deviation. Dual set screw locking prevents shaft slipping and loosening during operation. Integrated one-piece structure simplifies installation and replacement. Effective dust-proof sealing reduces long-term maintenance costs.

Application Scenarios

UCP311 pillow block bearings are widely used in heavy-duty conveyor systems, construction machinery, agricultural equipment, mining auxiliary machinery, large textile machines and automated production lines. Ideal for heavy-load, high-vibration and long-duration continuous rotation industrial working conditions.
