Product Overview: The NJ 208 Cylindrical Roller Bearing
The NJ 208 bearing is a high-performance component from our NJ 200 Series of Cylindrical Roller Bearings. Engineered to handle significant radial loads, this bearing features a single row of cylindrical rollers, which provides a large contact area with the raceways. Its design includes two fixed flanges on the outer ring and a single fixed flange on the inner ring, allowing the shaft to accommodate axial displacement in one direction relative to the housing. With precise dimensions of 40mm bore, 80mm outer diameter, and 18mm thickness, the NJ 208 is ideal for applications requiring high rigidity, excellent load capacity, and moderate axial location.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our NJ 208 bearings are manufactured to rigorous industry standards. This results in components that offer reliable performance, extended service life, and efficient operation in demanding industrial environments. The separable design of this bearing, where the inner ring can be mounted separately from the outer ring and roller assembly, simplifies the installation and maintenance processes.

Features of the NJ 208 Bearing
- High Radial Load Capacity: Designed with a large number of rollers for superior ability to support heavy radial forces.
- Axial Displacement Accommodation: Allows for axial movement in one direction, useful for accommodating thermal expansion or minor alignment changes.
- Rigid Structure: Provides excellent stiffness, crucial for maintaining precision in applications with varying loads.
- Separable Components: Inner ring, outer ring, and roller assembly can be mounted independently, simplifying installation and maintenance.
- Low Friction: Cylindrical rollers offer reduced rolling friction, leading to cooler operation and energy efficiency.
- High Speed Capability: Suitable for applications requiring relatively high rotational speeds due to the line contact between rollers and raceways.
- Durable Construction: Made from high-quality bearing steel to ensure longevity and resistance to wear under continuous operation.
