Product Overview: The NU 217 Cylindrical Roller Bearing
The NU 217 is a single-row cylindrical roller bearing engineered for high performance in demanding industrial environments. With principal dimensions of 85x150x28mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NU 200 Series. As part of the broader Cylindrical Roller Bearings category, the NU 217 is specifically designed to handle high radial loads at high speeds. Its NU design features two flanges on the outer ring and no flanges on the inner ring. This unique configuration allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precise industry standards, the NU 217 ensures operational reliability and longevity. The separable design, where the inner ring can be removed from the outer ring and roller assembly, greatly simplifies mounting, dismounting, and maintenance procedures. Trust our expertise as a premier supplier to provide high-quality bearings for your most critical machinery.
Key Features of the NU 217 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows the shaft to move axially in either direction relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring is separable, which simplifies installation and allows for interchangeability of components.
- High-Speed Performance: Engineered with a robust cage and optimized roller geometry to perform reliably at high rotational speeds.
- Enhanced Rigidity: Provides a high degree of stiffness, ensuring stable and precise shaft support.
- Low-Friction Operation: Designed to minimize friction and heat generation, which extends the bearing's service life and improves efficiency.
Common Applications
