Product Overview: N 317 Cylindrical Roller Bearing
The N 317 Cylindrical Roller Bearing is a high-capacity, single-row bearing designed for demanding industrial applications. With key dimensions of 85x180x41mm, this component is part of our robust N 300 Series within the broader Cylindrical Roller Bearings category. The 'N' designation indicates that the inner ring features two integral flanges, while the outer ring is flangeless. This specific design 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, especially where thermal expansion of the shaft occurs.
Engineered to support heavy radial loads at high speeds, the N 317 is an essential component in heavy machinery. Its separable design—where the outer ring can be mounted independently of the inner ring and roller assembly—greatly simplifies installation, inspection, and maintenance procedures. As a trusted supplier of industrial parts, we ensure our N 317 bearings meet stringent quality standards for reliable performance and extended service life.
Key Features of the N 317 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial forces.
- Axial Displacement Accommodation: The flangeless outer ring permits axial movement in both directions, compensating for shaft expansion and contraction.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies the assembly and fitting process.
- High-Speed Performance: Engineered for low friction, making it suitable for applications requiring high rotational speeds.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and wear resistance.
- Dimensional Stability: Precision-engineered to maintain its shape and function under heavy loads and high temperatures.
Common Applications
