Product Overview: The NUP 213NV Cylindrical Roller Bearing
The NUP 213NV is a high-performance single-row cylindrical roller bearing, engineered to precise dimensions of 65x120x23mm. As a key component in our NUP Series of Cylindrical Roller Bearings, its unique design is distinguished by two integral flanges on the outer ring and a single integral flange with a loose thrust collar on the inner ring. This configuration allows the bearing to act as a locating bearing, capable of accommodating axial loads and fixing the shaft's position in both directions. The 'NV' suffix typically indicates a polyamide cage, which offers excellent performance in high-speed applications and reduces operational noise.
Key Features of the NUP 213NV Bearing
- Bi-Directional Axial Location: The flange arrangement securely locates the shaft axially in both directions, providing excellent positional stability.
- High Radial Load Capacity: Designed with line contact between the rollers and raceways, this bearing can support heavy radial loads.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, simplifying installation and maintenance procedures.
- Polyamide Cage (NV): Features a robust and lightweight polyamide cage, suitable for high-speed operation, reducing friction, and minimizing noise.
- Durable Construction: Manufactured from high-quality bearing steel for superior strength, durability, and a long service life.
- Precision Engineering: Produced to strict industry standards to ensure dimensional and rotational accuracy for reliable performance.
Common Applications
- Industrial Gearboxes: Provides rigid support and axial location for gear shafts, ensuring precise mesh and power transmission.
- Electric Motors: Used to support motor shafts, handling both radial loads and fixing the rotor's axial position.
- Pumps and Compressors: Ensures the stable and efficient rotation of shafts in demanding fluid and gas handling equipment.
