Product Overview: The N 318 Cylindrical Roller Bearing
The N 318 Cylindrical Roller Bearing is a high-capacity, single-row bearing engineered for applications demanding robust performance under heavy radial loads. With principal dimensions of 90mm Bore Diameter, 190mm Outer Diameter, and 43mm Thickness, this bearing is a key component in heavy industrial machinery. As part of our N 300 Series, the N 318 features an inner ring with two integral flanges and a flangeless outer ring. This design 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.
Manufactured from high-quality bearing steel, our N 318 bearings offer excellent durability and operational reliability. The line contact between the rollers and raceways provides a high degree of stiffness and superior radial load-carrying capacity.

Key Features of the N 318 Bearing
- High Radial Load Capacity: Designed with line contact between rollers and raceways to support heavy radial forces.
- Axial Displacement Accommodation: The flangeless outer ring allows for axial movement, compensating for thermal expansion of the shaft.
- Separable Design: The inner ring can be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance.
- High Stiffness: Provides rigid support for rotating shafts, enhancing machine precision and stability.
- Durable Construction: Made from high-purity, through-hardened bearing steel for long service life and resistance to wear.
- Low Friction Operation: Precision engineering minimizes frictional torque, leading to cooler operation and improved efficiency.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty transmission systems.
- Large Electric Motors: Used in high-power motors where radial loads are significant.
