Product Overview: The NJ 2311 Cylindrical Roller Bearing
The NJ 2311 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 55x120x43mm, this bearing is a key component in our Cylindrical Roller Bearings collection. Its specific design, part of the versatile NJ Series, 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, making it suitable for providing axial location.
As a leading supplier of industrial bearings, we ensure our NJ 2311 bearings meet stringent quality standards for performance and durability. The line contact between the rollers and raceways provides a high degree of stiffness and allows for heavy radial load support, making it an excellent choice for machinery operating under rigorous conditions. Explore the complete NJ 2300 Series for a range of sizes to meet your specific needs.
Features of the NJ 2311 Bearing
- Single-Direction Axial Location: The flange arrangement on the inner and outer rings allows the bearing to locate a shaft axially in one direction.
- High Radial Load Capacity: Designed with line contact between rollers and raceways, enabling it to support heavy radial loads.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, simplifying installation and maintenance.
- High-Speed Capability: Optimized internal geometry reduces friction and heat generation, making it suitable for high-speed operation.
- Robust Construction: Manufactured from high-quality bearing steel for exceptional hardness, wear resistance, and long service life.
- Accommodates Thermal Expansion: Allows for axial displacement, which can compensate for shaft expansion or contraction due to temperature changes.
