Product Overview: The NJ 305 Cylindrical Roller Bearing
The NJ 305 is a single-row cylindrical roller bearing designed to handle high radial loads and provide axial location for a shaft in one direction. With its principal dimensions of 25mm bore diameter, 62mm outer diameter, and 17mm thickness, this bearing is a robust component in our NJ 300 Series. As part of our comprehensive range of Cylindrical Roller Bearings, the NJ 305 is engineered for high performance and durability in demanding industrial environments. Its unique design features two flanges on the outer ring and a single flange on the inner ring, making it ideal for applications requiring one-way axial support.
As a leading supplier of industrial bearings, we ensure our NJ 305 bearings meet stringent quality standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures, saving valuable time and effort.
Key Features of the NJ 305 Bearing
- Single Direction Axial Location: The flange arrangement provides effective axial location for the shaft in one direction.
- High Radial Load Capacity: The line contact between rollers and raceways allows for the accommodation of very high radial forces.
- Separable Design: The inner ring can be dismounted, facilitating easier mounting, dismounting, and inspection routines.
- High-Speed Capability: Engineered with low-friction characteristics, making it suitable for applications with high rotational speeds.
- Robust Construction: Manufactured from high-quality bearing steel for superior strength, durability, and resistance to wear.
- Dimensional Stability: Precision engineering ensures consistent performance and interchangeability.
