Product Overview: The NU 219 Cylindrical Roller Bearing
The NU 219 Cylindrical Roller Bearing is a high-performance component engineered to handle substantial radial loads at high speeds. With precise dimensions of 95mm Bore Diameter, 170mm Outer Diameter, and 32mm Thickness, this bearing is a key part of our Cylindrical Roller Bearings collection. The 'NU' designation signifies a 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 an ideal choice for non-locating bearing positions, especially where thermal expansion occurs.
As a leading supplier of industrial components, we ensure our NU 219 bearings, part of the NU 200 Series, are manufactured to the highest industry standards. Its separable design—where the inner ring can be mounted independently of the outer ring and roller assembly—greatly simplifies installation, inspection, and maintenance procedures.

Key Features of the NU 219 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 for free axial movement of the shaft, compensating for thermal expansion and mounting inaccuracies.
- Separable Design: The inner ring is separable from the outer ring and roller cage assembly, facilitating easy mounting and dismounting.
- High-Speed Performance: Engineered with a robust cage and optimized internal geometry to support high rotational speeds with low friction.
- Robust Construction: Manufactured from high-quality, clean bearing steel for enhanced durability, wear resistance, and long service life.
- Interchangeability: Produced to standard dimensions, ensuring it can be easily interchanged with other manufacturers' equivalent parts.
Common Applications of NU 219 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, especially in non-locating positions.
- Electric Motors: Used in large motors to support the rotor shaft while allowing for thermal expansion.
- Pumps and Compressors: Ensures smooth and efficient operation in various industrial fluid and gas handling equipment.
- Construction Machinery: Ideal for heavy-duty equipment like excavators, loaders, and cranes where high radial forces are common.
