Product Overview: The NU 215 Cylindrical Roller Bearing
The NU 215 is a high-performance single-row cylindrical roller bearing with principal dimensions of 75x130x25mm. As a key component in our Cylindrical Roller Bearings collection, it is designed to handle high radial loads at high speeds. This bearing is part of the versatile NU 200 Series, known for its specific design and wide range of applications. The 'NU' designation signifies that the outer ring has two integral flanges, while the inner ring is flangeless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions.
Engineered for reliability, the NU 215's line contact between the rollers and raceways minimizes edge stresses, ensuring a long service life even under heavy loads. Its separable design simplifies the mounting and dismounting process, as the inner ring can be installed independently of the outer ring and roller assembly. This feature is particularly beneficial for applications requiring an interference fit for both rings.
Key Features of the NU 215 Bearing
- High Radial Load Capacity: Designed with line contact between rollers and raceways to support substantial radial forces.
- Accommodates Axial Displacement: The NU design allows the shaft to move axially relative to the housing, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner ring can be separated from the outer ring and roller assembly, facilitating easier installation and maintenance.
- High-Speed Capability: Optimized internal geometry and cage design enable smooth operation at high rotational speeds with low friction.
- Robust Construction: Manufactured from high-quality bearing steel for exceptional durability and resistance to wear and fatigue.
- Interchangeability: Produced to strict industry standards, ensuring dimensional and running accuracy for easy replacement.
