Product Overview: The NJ 417 Cylindrical Roller Bearing
The NJ 417 is a high-capacity single-row cylindrical roller bearing, engineered to handle substantial radial loads while accommodating axial displacement in one direction. With dimensions of 85x210x52mm, this robust component is a key part of our NJ 400 Series within the broader Cylindrical Roller Bearings category. The 'NJ' designation signifies a design with two integral flanges on the inner ring and one on the outer ring, allowing it to provide axial shaft location in a single direction. This feature makes it ideal for applications requiring precise shaft guidance under heavy radial stress.
As a premier supplier of industrial mechanical parts, we guarantee our NJ 417 bearings are manufactured to the highest industry standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies both installation and maintenance procedures. This bearing is a reliable choice for demanding industrial environments where performance and durability are paramount.
Features of the NJ 417 Bearing
- Single-Direction Axial Location: The flange arrangement provides effective shaft guidance and location in one axial direction.
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of very heavy radial loads.
- Separable Design: The inner ring can be dismounted, which facilitates easier mounting, dismounting, and inspection routines.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
- Interchangeability: Produced to standardized dimensions, ensuring it can be interchanged with other manufacturers' NJ 417 bearings.
Applications of NJ 417 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces typical in gear systems.
- Electric Motors: Used as a locating bearing on drive shafts in large industrial motors.
- Pumps and Compressors: Ensures the stable rotation of impellers and crankshafts under heavy operational loads.
- Construction and Mining Equipment: Ideal for use in heavy machinery like excavators, conveyors, and rock crushers.
- Wind Turbines: Supports the main shaft and gearbox components, withstanding significant and variable loads.
- Rolling Mills: Employed in the support rollers of steel and metal processing machinery.
- Machine Tool Spindles: Offers the rigidity and precision required for high-performance cutting and grinding applications.
Benefits of Using the NJ 417 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads and provide axial location reduces wear on other components.
- Simplified Assembly: The separable design streamlines the installation process, reducing machine downtime.
- Extended Service Life: The robust materials and design ensure long-term performance even in harsh operating conditions.
- Improved Operational Efficiency: Low-friction characteristics contribute to reduced energy consumption and smoother machinery operation.
- Versatile Shaft Arrangement: Accommodates axial expansion or contraction of the shaft relative to the housing.
- Reduced Maintenance Requirements: The durable construction minimizes the risk of premature failure, lowering overall maintenance costs.
