PDN Type Plummer Block Housings

Series by JAYCO Engineering India

Precision Two-Bearing Housings for Overhung Shaft & High-Speed Applications

JAYCO PDN Type Plummer Block Housings are extra heavy-duty, precision-machined, two-bearing housings, specifically designed to support overhung shafts used in industrial fans, pumps, transmission systems, and rotating equipment.

The PDN series is engineered to deliver vibration-free operation, high rotational accuracy, and long bearing life, making it ideal for relatively high-speed and dynamically loaded applications.

Built for Accuracy. Designed for Speed. Trusted for Stability.

The most critical design feature of JAYCO PDN housings is that both bearing seats are machined concentrically in a single setting, ensuring:

Perfect coaxial alignment

Minimal vibration

Reduced noise

Extended bearing and seal life

This design advantage is essential for fan impellers and overhung shaft arrangements, where imbalance and misalignment can cause severe vibration.

Typical Applications

JAYCO PDN & PDD housings are primarily used to support overhung shafts, especially where an impeller or rotating element is mounted on an extended shaft end.

Common Applications:

Industrial Fans & Blowers

Centrifugal Pumps

Circular Saws

Transmission Systems

Rotating Machinery Assemblies

Due to their accurate machining and rigid construction, PDN housings are ideal for vibration-free, high-speed operation.
