Product Overview: The NJ 2205 Cylindrical Roller Bearing
The NJ 2205 is a high-performance cylindrical roller bearing, meticulously engineered to handle demanding industrial applications. With key dimensions of a 25mm bore diameter, 52mm outer diameter, and 18mm thickness, this bearing is a vital component in our Cylindrical Roller Bearings collection. Part of the specialized NJ Series and the robust NJ 2200 Series, the NJ 2205 is designed with two integral flanges on the outer ring and one on the inner ring. This configuration allows it to accommodate heavy radial loads while also providing axial location for a shaft in one direction.
Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures. This makes the NJ 2205 an excellent choice for machinery where reliability and ease of service are paramount.
Key Features of the NJ 2205 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the support of heavy radial forces.
- Single-Direction Axial Location: Features a unique flange arrangement that guides and locates the shaft axially in one direction, preventing unwanted movement.
- Separable Design: The inner ring is detachable from the outer ring and roller cage assembly, facilitating straightforward mounting and dismounting.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Durable Construction: Manufactured from high-grade bearing steel to ensure exceptional hardness, wear resistance, and a long operational lifespan.
- Precision Engineering: Produced to strict tolerances to guarantee consistent and reliable performance in critical machinery.
