Product Overview: The NJ 317 Cylindrical Roller Bearing
The NJ 317 bearing is a high-performance single-row cylindrical roller bearing, renowned for its exceptional radial load capacity and suitability for high-speed applications. With precise dimensions of 85mm bore diameter, 180mm outer diameter, and 41mm thickness, this bearing is a vital component within our comprehensive NJ 300 Series and broader NJ Series of Cylindrical Roller Bearings. Its design features rollers that are precisely guided by flanges on one ring, while the other ring is flangeless, allowing for axial displacement of the shaft relative to the housing. This configuration makes the NJ 317 capable of accommodating moderate axial loads in one direction in addition to significant radial loads, offering superior stiffness and operational reliability in demanding industrial environments. As a trusted supplier of industrial bearings, we ensure our NJ 317 bearings meet stringent industry standards for consistent performance and long service life.
Key Features of the NJ 317 Bearing
- High Radial Load Capacity: Engineered with a large number of rollers to distribute loads over a wider area, enabling the bearing to withstand substantial radial forces.
