Product Overview: The NU 2311 Cylindrical Roller Bearing
The NU 2311 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 55x120x43mm, this bearing is a key component in our NU 2300 Series, part of the broader Cylindrical Roller Bearings collection. The 'NU' designation signifies that the bearing features two integral flanges on the outer ring and a flangeless inner ring. This design is crucial for applications requiring accommodation of axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions.
Engineered to handle heavy radial loads at high speeds, the NU 2311 is manufactured from high-purity, hardened bearing steel to ensure exceptional durability and performance. Its separable design, with a removable inner ring, simplifies the mounting and dismounting process, which is particularly advantageous for maintenance operations in heavy machinery. Trust in our expertise as a leading supplier of industrial components to provide reliable and precision-engineered bearings for your most critical operations.
Features of the NU 2311 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial forces.
- Axial Displacement: The NU design with a flangeless inner ring accommodates axial expansion and contraction of the shaft.
