Product Overview: The NU 209 Cylindrical Roller Bearing
The NU 209 is a single-row cylindrical roller bearing engineered for applications demanding high radial load capacity and the ability to accommodate axial displacement. As a key component in our Cylindrical Roller Bearings range, and specifically part of the NU 200 Series, this bearing features two integral flanges on the inner ring and a flangeless outer ring. This design allows the shaft to move axially relative to the housing in both directions, making it ideal for compensating for thermal expansion or minor mounting inaccuracies.
Manufactured to precise industry standards with dimensions of 45x85x19mm, the NU 209 bearing is a non-locating bearing that provides robust support for rotating shafts. Its separable design—where the inner ring can be mounted independently of the outer ring and roller assembly—greatly simplifies both installation and maintenance procedures in complex machinery. Trust in our expertise as a premier supplier of industrial parts to provide reliable components for your most demanding applications.
Key Features of the NU 209 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement Accommodation: The NU design permits axial movement of the shaft relative to the housing, ideal for thermal expansion.
- Separable Design: The inner and outer rings can be mounted separately, simplifying assembly and maintenance processes.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high-speed operations.
- Robust Construction: Made from high-purity, hardened bearing steel for exceptional durability and a long service life.
- Interchangeability: Manufactured to standardized dimensions for easy replacement and integration into existing systems.
