Product Overview: The NU 218 Cylindrical Roller Bearing
The NU 218 bearing is a high-performance, single-row cylindrical roller bearing designed for applications demanding high radial load capacity and high-speed operation. With principal dimensions of 90mm Bore Diameter, 160mm Outer Diameter, and 30mm Thickness, this component is a key part of our NU 200 Series. As a prominent type within our Cylindrical Roller Bearings range, the NU 218 features a unique design with 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 non-locating bearing positions.
Manufactured from high-quality bearing steel, the NU 218 ensures exceptional durability and performance in challenging industrial environments. Its separable design allows the inner ring to be mounted independently from the outer ring and roller assembly, simplifying both installation and maintenance procedures.

Key Features of the NU 218 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Accommodates Axial Displacement: The flangeless inner ring design permits axial movement between the shaft and housing, compensating for thermal expansion.
- Separable Design: The inner ring, outer ring, and roller assembly are separable, facilitating easier mounting, dismounting, and inspection.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-rotational speed applications.
- Robust Construction: Made from high-grade, through-hardened bearing steel for enhanced strength and extended service life.
- Interchangeability: Manufactured to industry-standard dimensions for easy replacement and system integration.
