Product Overview: The NJ 213 Cylindrical Roller Bearing
The NJ 213 is a high-performance single-row cylindrical roller bearing, engineered to handle heavy radial loads and high-speed operations. With principal dimensions of 65mm bore diameter, 120mm outer diameter, and 23mm thickness, this bearing is a crucial component in demanding industrial machinery. As part of our extensive Cylindrical Roller Bearings collection, the NJ 213 features a unique design with two integral flanges on the outer ring and one on the inner ring. This configuration allows it to locate the shaft axially in one direction, making it suitable for applications requiring both radial support and single-direction axial positioning.
Manufactured to precise industry standards, the NJ 213 belongs to the NJ 200 Series, known for its robustness and reliability. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures. Trust our expertise as a leading supplier of industrial parts to provide components that enhance your machinery's efficiency and lifespan.
Features of the NJ 213 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows the bearing to support very heavy radial loads.
- Single-Direction Axial Location: The flange arrangement enables the bearing to guide the shaft axially in one direction, acting as a locating bearing.
- Separable Design: The inner ring is separable from the outer ring and roller cage assembly, which greatly simplifies mounting and dismounting.
- High-Speed Performance: Engineered with an optimized internal geometry to accommodate high rotational speeds with low friction.
- Durable Construction: Made from premium-grade bearing steel for superior hardness, wear resistance, and long-term durability.
- Interchangeability: Components are interchangeable, allowing for easier maintenance and replacement.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy loads typical in power transmission.
- Electric Motors: Used in large motors to support the rotor shaft and manage high radial forces.
