PDN Series (200,300)
Precision Two-Bearing Housings for Overhung Shaft & High-Speed Applications
JAYCO Engineering manufactures PDN Type Plummer Block Housings, specially engineered for overhung shaft applications, high rotational accuracy, and vibration-free performance in demanding industrial environments. These extra heavy-duty two-bearing housings are widely used in industrial fans, blowers, pumps, transmission systems, and rotating machinery where precise shaft alignment and stable high-speed operation are critical. Designed with concentric machining accuracy and robust cast iron construction, JAYCO PDN housings ensure long bearing life, reduced vibration, minimal noise, and superior operational stability.
Precision-Machined for Vibration-Free Performance
The key advantage of JAYCO PDN housings is that both bearing seats are machined concentrically in a single setup, ensuring:
- Accurate coaxial alignment
- Reduced shaft misalignment
- Minimal vibration & noise
- Smooth high-speed rotation
- Extended bearing and seal life
This precision design makes PDN housings ideal for overhung impeller shafts, where imbalance and alignment issues can significantly affect machine performance.
