Product Overview: The NJ 2213 Cylindrical Roller Bearing
The NJ 2213 is a high-performance single-row cylindrical roller bearing with dimensions of 65x120x31mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to handle high radial loads and accommodate axial displacement in one direction. The 'NJ' designation signifies that the outer ring has a single flange, while the inner ring has two, enabling it to provide axial location for a shaft in one direction. This design makes it a versatile solution for heavy-duty industrial applications requiring both robust radial support and precise shaft guidance.
Part of the respected NJ 2200 Series, the NJ 2213 bearing features a separable design, which means the inner ring with the roller and cage assembly can be mounted independently of the outer ring. This greatly simplifies the installation, maintenance, and inspection processes. Manufactured from premium-grade bearing steel, it ensures durability and a long service life even under demanding operational conditions.
Key Features of the NJ 2213 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very high radial forces.
- Axial Load in One Direction: The integral flanges on the inner and outer rings enable the bearing to locate the shaft axially in a single direction.
- Separable Design: The inner and outer rings can be mounted separately, simplifying assembly and facilitating easier maintenance checks.
- High-Speed Performance: Engineered for low friction and optimized internal geometry, making it suitable for high-speed applications.
- Dimensional Stability: Manufactured to precise tolerances, ensuring consistent performance and interchangeability.
- Durable Construction: Made from high-quality, clean bearing steel for exceptional wear resistance and longevity.
