Product Overview: The NJ 407 Cylindrical Roller Bearing
The NJ 407 is a single-row cylindrical roller bearing engineered for high-performance applications requiring both substantial radial load support and single-direction axial positioning. With key dimensions of 35x90x23mm (Bore x Outer Diameter x Thickness), this bearing is a vital component in a wide array of industrial machinery. As part of our extensive Cylindrical Roller Bearings collection, the NJ 407 features two integral flanges on the outer ring and a single integral flange on the inner ring. This design allows it to function as a locating bearing, guiding the shaft axially in one direction while accommodating slight axial displacement in the other.
Manufactured to precise industry standards, the NJ 407 bearing ensures reliability and durability. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures. This bearing is an excellent choice for applications where high radial loads and moderate speeds are expected. Explore our complete NJ 400 Series for similar high-quality solutions.
Features of the NJ 407 Bearing
- Single-Direction Axial Location: The L-shaped inner ring allows the bearing to locate and support the shaft axially in one direction.
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Separable Design: The inner and outer rings can be separated, which facilitates easier mounting, dismounting, and inspection.
- High-Speed Capability: Engineered for efficient operation at high rotational speeds with low friction.
- Durable Construction: Made from high-grade bearing steel for superior strength, wear resistance, and long service life.
- Accommodates Axial Displacement: Allows for minor axial movement of the shaft relative to the housing, compensating for thermal expansion.
