Product Overview: The NJ 220 Cylindrical Roller Bearing
The NJ 220 is a high-performance cylindrical roller bearing with principal dimensions of 100x180x34mm. As a key component in our Cylindrical Roller Bearings range, this bearing is engineered to handle heavy radial loads and high speeds. The NJ design features two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in one direction, while also providing axial location in the other direction. Part of the versatile NJ 200 Series, the NJ 220 is a separable bearing, meaning the inner ring with the roller and cage assembly can be mounted independently of the outer ring, which significantly simplifies installation and maintenance procedures.
Features of the NJ 220 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Location Capability: Designed to locate the shaft axially in a single direction, making it suitable for certain fixed-end applications.
- Separable Design: The inner and outer rings can be mounted separately, allowing for easier and more efficient assembly and maintenance.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, enabling reliable operation at high rotational speeds.
- Robust Construction: Manufactured from high-quality, clean bearing steel to ensure durability and extend service life under demanding conditions.
- Interchangeability: Produced to strict industry standards, ensuring dimensional and running accuracy for easy replacement.
