Product Overview: The NU 2212 Cylindrical Roller Bearing
The NU 2212 is a high-capacity, single-row cylindrical roller bearing designed for applications demanding robust performance and reliability. With dimensions of 60x110x28mm, this bearing is a key component in our NU Series, part of the broader Cylindrical Roller Bearings collection. The 'NU' designation signifies a specific design where the outer ring has two integral flanges, and the inner ring is flangeless. This configuration is crucial as it accommodates axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions.
Manufactured to precise industry standards, the NU 2212 bearing's design minimizes friction and heat generation, ensuring smooth operation even at high speeds. Its separable nature, with a detachable inner ring, simplifies both mounting and dismounting processes, reducing downtime during maintenance. This bearing is engineered to handle heavy radial loads, making it an essential part for a wide range of industrial machinery.
Key Features of the NU 2212 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement: The NU design allows for axial movement, effectively compensating for shaft expansion or mounting inaccuracies.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, facilitating easy installation and inspection.
- High-Speed Performance: Engineered for low friction, making it suitable for applications with high rotational speeds.
- Robust Construction: Made from high-quality, clean bearing steel to ensure durability and a long service life.
- Interchangeability: Components are interchangeable, allowing for greater flexibility in mounting and maintenance.
