Product Overview: The NUP 2214 Cylindrical Roller Bearing
The NUP 2214 is a high-performance single-row cylindrical roller bearing designed to handle demanding industrial applications. With key dimensions of 70x125x31mm (Bore x Outer Diameter x Thickness), this bearing is a crucial component in our NUP 2200 Series. As part of the extensive Cylindrical Roller Bearings family, the NUP 2214 is engineered for high radial load capacity and moderate axial loads in both directions. Its unique NUP design features two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring, allowing it to locate the shaft axially in two directions.
This bearing's separable design, where the inner and outer rings can be mounted independently, greatly simplifies the installation and maintenance process. Manufactured from high-quality bearing steel, the NUP 2214 offers excellent durability and reliability, making it an ideal choice for machinery operating under heavy loads and at high speeds.
Key Features of the NUP 2214 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very heavy radial loads.
- Axial Load Support: The NUP flange configuration enables the bearing to locate the shaft axially and carry incidental axial loads in both directions.
- Separable Design: The inner ring, outer ring, and roller cage assembly are separable, facilitating easier mounting, dismounting, and inspection.
- High-Speed Performance: Engineered with precision cages that are suitable for high rotational speeds, reducing friction and operational heat.
- Robust Construction: Manufactured from premium, high-purity bearing steel for superior strength, wear resistance, and extended service life.
- Dimensional Stability: Precision-machined to tight tolerances, ensuring consistent and reliable performance in demanding environments.
