Product Overview: N 308 Cylindrical Roller Bearing
The N 308 bearing is a high-performance single-row cylindrical roller bearing with dimensions of 40x90x23mm. As a key component in our N 300 Series, this bearing is engineered to handle high radial loads at high rotational speeds. Its distinctive "N" type design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions.
Manufactured to exacting standards, the N 308 offers exceptional reliability and a long service life in demanding industrial environments. Its separable design—where the inner ring can be mounted independently of the outer ring and roller assembly—simplifies both installation and maintenance procedures.

Key Features of the N 308 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
- Axial Displacement Accommodation: The N-type design permits thermal expansion or contraction of the shaft without inducing axial stress.
- 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 low-friction characteristics, making it suitable for applications with high rotational speeds.
- Robust Construction: Made from high-quality bearing steel for superior durability, wear resistance, and operational longevity.
- High Stiffness: Provides a high degree of rigidity, ensuring stable shaft support under load.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts in transmission systems.
- Pumps and Compressors: Used in industrial pumps to support rotating shafts under heavy radial forces.
- Electric Motors: Ideal for non-locating bearing positions in large electric motors.
- Construction Machinery: Employed in heavy equipment like excavators and cranes where high radial loads are common.
