Product Overview: The NU 2220 Cylindrical Roller Bearing
The NU 2220 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 100x180x46mm, this bearing is a crucial component in our NU 2200 Series, part of the broader Cylindrical Roller Bearings collection. The 'NU' design features two integral flanges on the outer ring and a flangeless inner ring. 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 in machinery where thermal expansion occurs.
As a leading supplier of industrial components, we ensure our NU 2220 bearings are manufactured to the highest industry standards. The line contact between the rollers and raceways provides a high radial load carrying capacity and makes this bearing suitable for high-speed operation. Its separable design, where the inner ring can be mounted separately from the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.
Key Features of the NU 2220 Bearing
- High Radial Load Capacity: Engineered to support heavy radial loads due to the line contact between rollers and raceways.
- Axial Displacement: The NU design accommodates axial expansion and contraction of the shaft, preventing stress from thermal variations.
- Separable Design: The inner ring is separable from the outer ring and cage assembly, allowing for easier mounting and dismounting.
- Low Friction: Optimized internal geometry reduces friction and heat generation, leading to more efficient operation and longer service life.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and wear resistance.
- High-Speed Capability: Suitable for applications requiring high rotational speeds without compromising on load capacity.
