Product Overview: The NU 307 Cylindrical Roller Bearing
The NU 307 Cylindrical Roller Bearing is a high-capacity, non-locating bearing designed for demanding industrial applications. With dimensions of 35x80x21mm, this bearing is a key component in our NU 300 Series, part of the broader Cylindrical Roller Bearings collection. Its defining feature is the NU design, which includes 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 ideal for use as a non-locating bearing.
Engineered to handle high radial loads at high speeds, the NU 307's line contact between the rollers and raceways minimizes stress concentration. The separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures. This robust bearing is a reliable choice for machinery where durability and precision are paramount.
Key Features of the NU 307 Bearing
- High Radial Load Capacity: Line contact between rollers and raceways provides excellent support for heavy radial forces.
- Separable Design: The inner ring is separable, facilitating easier mounting and dismounting processes.
- Axial Displacement Accommodation: The NU design allows for thermal expansion and contraction of the shaft without inducing axial stress.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed operations.
- Robust Construction: Manufactured from premium-grade bearing steel for exceptional durability and long service life.
- Interchangeability: Produced to standard ISO dimensions, ensuring interchangeability with other manufacturers' parts.
Common Applications
