Product Overview: The NJ 207 Cylindrical Roller Bearing
The NJ 207 is a high-capacity cylindrical roller bearing with dimensions of 35x72x17mm. As a key component in our Cylindrical Roller Bearings range, it is part of the versatile NJ 200 Series. The 'NJ' designation signifies a specific design with two integral flanges on the outer ring and one on the inner ring. This configuration allows the bearing to accommodate high radial loads while also providing axial location for a shaft in one direction. Its separable design simplifies the mounting and dismounting process, making it a practical choice for a wide array of industrial machinery.
Manufactured to exacting standards, the NJ 207 bearing features line contact between the rollers and raceways, which distributes loads over a larger area and provides high stiffness. This makes it exceptionally well-suited for applications demanding robust performance and precision. As a premier supplier of industrial components, we ensure our NJ 207 bearings deliver reliability and a long service life in challenging operational environments.
Key Features of the NJ 207 Bearing
- Single-Direction Axial Location: The flange arrangement allows the bearing to locate the shaft axially in one direction, preventing unwanted movement.
- High Radial Load Capacity: Engineered with cylindrical rollers that provide a large contact area, enabling it to support heavy radial forces.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- High Stiffness: The line contact geometry between rollers and raceways minimizes deformation under load, ensuring high operational rigidity.
- Low Friction Operation: Precision engineering ensures smooth rolling, which reduces operating temperature and conserves energy.
- Durable Construction: Made from high-quality, through-hardened bearing steel for superior durability and resistance to wear and fatigue.
