Product Overview: The NUP 306 Cylindrical Roller Bearing
The NUP 306 is a single-row cylindrical roller bearing designed for high-performance applications. With principal dimensions of 30x72x19mm, this bearing is part of our robust NUP 300 Series within the broader Cylindrical Roller Bearings category. The NUP design is particularly advantageous as it is engineered to locate the shaft axially in both directions. This is achieved through its unique construction, featuring two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring. This configuration makes the NUP 306 an excellent choice for applications requiring precise shaft positioning and the ability to handle substantial radial loads at high speeds.
Features of the NUP 306 Bearing
- Bi-Directional Axial Location: Uniquely designed to fix the position of a shaft against the housing in both axial directions.
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the accommodation of heavy radial loads.
- High-Speed Capability: Engineered for low friction and optimized internal geometry, making it suitable for high rotational speeds.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, simplifying installation and maintenance procedures.
- Enhanced Durability: Manufactured from high-quality, clean bearing steel to ensure long service life and reliability under demanding conditions.
- Component Interchangeability: The separable components are interchangeable, offering flexibility during assembly and replacement.
Common Applications
- Industrial Gearboxes: Provides rigid support for gears and shafts, ensuring precise meshing and efficient power transmission.
- Electric Motors: Used as locating bearings on motor shafts to handle radial loads and maintain rotor position.
