Product Overview: The NJ 334 Cylindrical Roller Bearing
The NJ 334 is a high-capacity single-row cylindrical roller bearing, engineered to handle heavy radial loads and provide axial location for a shaft in one direction. With dimensions of 170x360x72mm, this bearing is a robust component in our Cylindrical Roller Bearings collection. The NJ design features two integral flanges on the inner ring and one on the outer ring, making it ideal for applications requiring shaft guidance. Its separable design allows the inner and outer rings to be mounted independently, simplifying installation and maintenance procedures.
As part of the NJ 300 Series, the NJ 334 is manufactured to precise tolerances from high-quality bearing steel, ensuring durability and reliable performance in demanding industrial environments. The line contact between the rollers and raceways provides superior load-carrying capability and rigidity, making it a preferred choice for heavy machinery. Explore our full range of NJ Series bearings to find the perfect solution for your application.
Features of the NJ 334 Bearing
- Single-Direction Axial Location: Designed to locate the shaft axially in one direction, preventing unwanted movement.
- High Radial Load Capacity: The cylindrical rollers and raceway geometry are optimized for accommodating very heavy radial loads.
