Product Overview: The NJ 319 Cylindrical Roller Bearing
The NJ 319 Cylindrical Roller Bearing is a high-performance component engineered to support substantial radial loads at high speeds. With precise dimensions of 95x200x45mm (Bore x Outer Diameter x Thickness), this bearing is a key part of our NJ 300 Series and the broader Cylindrical Roller Bearings collection. The NJ design features two integral flanges on the outer ring and a single integral flange on the inner ring, allowing it to provide axial location for a shaft in one direction. This makes it an excellent choice for applications requiring both heavy radial support and single-direction axial guidance.
As a premier supplier of industrial mechanical parts, we ensure our NJ 319 bearings are manufactured to the highest industry standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies both installation and maintenance procedures. This bearing is essential for the reliability and efficiency of heavy-duty machinery across various sectors.
Key Features of the NJ 319 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very high radial forces.
- Single-Direction Axial Location: The flange configuration enables the bearing to locate the shaft axially in one direction, preventing unwanted movement.
- Separable Design: The inner ring is separable, facilitating easier mounting, dismounting, and inspection processes.
- High-Speed Performance: Engineered with precision cages that are suitable for high rotational speeds, reducing friction and heat generation.
- Robust Construction: Manufactured from premium-grade bearing steel for superior durability, wear resistance, and a long operational lifespan.
- Dimensional Stability: Heat-treated to ensure consistent performance even under fluctuating temperatures and heavy loads.
Common Applications of NJ 319 Bearings
