Product Overview: The NJ 405 Cylindrical Roller Bearing
The NJ 405 is a high-performance single-row cylindrical roller bearing designed to handle heavy radial loads and high speeds. With principal dimensions of 25x62x17mm, this bearing is a crucial component in our NJ 400 Series line-up within the broader Cylindrical Roller Bearings category. The 'NJ' designation signifies a specific flange configuration: two integral flanges on the outer ring and one on the inner ring. This design allows the bearing to locate a shaft axially in one direction, making it suitable for applications requiring both radial support and axial positioning.
Manufactured to exacting standards, the NJ 405 features a separable design, which means the inner ring with its roller and cage assembly can be mounted independently from the outer ring. This simplifies installation, inspection, and maintenance procedures, especially in confined spaces. Its robust construction ensures long service life and reliable operation in demanding industrial environments.
Key Features of the NJ 405 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the accommodation of very heavy radial loads.
- Single-Direction Axial Location: The flange arrangement provides positive axial location for the shaft in one direction.
- Separable Design: The inner and outer rings can be separated, facilitating easier mounting and dismounting processes.
- Low Friction Operation: Precision engineering of the rollers and raceways minimizes friction, reducing heat generation and energy consumption.
- High-Speed Capability: Suitable for applications that operate at high rotational speeds without compromising performance.
- Durable Steel Construction: Made from high-quality, clean bearing steel for maximum durability and resistance to wear and fatigue.
