Product Overview: The NJ 2211 Cylindrical Roller Bearing
The NJ 2211 is a high-performance single-row cylindrical roller bearing with principal dimensions of 55x100x25mm. As a key component in our NJ Series, this bearing is engineered to accommodate heavy radial loads and high speeds. The NJ design features two integral flanges on the outer ring and one on the inner ring, which allows it to provide axial location for a shaft in one direction. This makes it an excellent choice for applications requiring both robust radial support and single-direction axial positioning. The inner and outer rings are separable, simplifying the mounting and dismounting process, which is particularly useful for maintenance.
Manufactured from high-quality bearing steel, the NJ 2211 ensures durability and a long service life even in demanding industrial environments. As a leading supplier, we offer a comprehensive range of Cylindrical Roller Bearings to meet the diverse needs of modern machinery. The optimized internal geometry of the NJ 2211 minimizes friction, reducing heat generation and improving operational efficiency.
Key Features of the NJ 2211 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Single-Direction Axial Location: The flange configuration allows the bearing to locate the shaft axially in one direction.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance.
