Product Overview: The NU 212 Cylindrical Roller Bearing
The NU 212 bearing is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 60x110x22mm, this component is part of our NU 200 Series, a key range within our broader Cylindrical Roller Bearings collection. The 'NU' designation signifies that the outer ring has two integral flanges while the inner ring is flangeless. This unique configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion or potential shaft deflection.
As a leading supplier of industrial components, we ensure our NU 212 bearings are manufactured to precise industry standards, delivering exceptional performance under high radial loads and speeds. The separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, simplifies installation and maintenance procedures. This makes the NU 212 a versatile and reliable choice for a wide array of machinery.
Features of the NU 212 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The flangeless inner ring design allows for axial movement, preventing stress from thermal shaft expansion.
- Separable Design: The inner ring can be removed, facilitating easier mounting, dismounting, and inspection.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, making it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and a long service life.
- Interchangeability: Produced to standard dimensions, allowing for easy replacement and sourcing.
