Product Overview: The NJ 328 Cylindrical Roller Bearing
The NJ 328 is a high-capacity single-row cylindrical roller bearing designed for heavy-duty industrial applications. With primary dimensions of 140mm Bore Diameter, 300mm Outer Diameter, and 102mm Thickness, this bearing is engineered to handle substantial radial loads at high speeds. As a key component in our NJ 300 Series, the NJ 328 features a distinctive design with two flanges on the outer ring and a single flange on the inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft in one direction, providing precise axial location.
Manufactured from premium-grade bearing steel, the NJ 328 offers exceptional durability and operational reliability. Its separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures. This makes it an ideal choice for machinery where ease of assembly is crucial. For a comprehensive selection of similar components, explore our full range of Cylindrical Roller Bearings.
Key Features of the NJ 328 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the accommodation of very high radial forces.
- Single-Direction Axial Location: The flange arrangement enables the bearing to locate the shaft axially in one direction, acting as a one-way locating bearing.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, facilitating easier mounting and dismounting.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust and Durable: Constructed from high-quality, through-hardened bearing steel for extended service life and resistance to wear.
- Interchangeability: Manufactured to standard ISO dimensions, ensuring it can be interchanged with other manufacturers' equivalent parts.
