Product Overview: The NJ 2217 Cylindrical Roller Bearing
The NJ 2217 is a high-capacity single-row cylindrical roller bearing, meticulously engineered to handle demanding industrial applications. With key dimensions of 85x150x36mm (Bore x Outer Diameter x Thickness), this bearing is a vital component within our NJ 2200 Series. Its design features two integral flanges on the outer ring and a single flange on the inner ring. This configuration allows the bearing to accommodate high radial loads and locate the shaft axially in one direction, making it an excellent choice for applications requiring precise shaft guidance and support under heavy stress. As a leading supplier of industrial components, we ensure our NJ 2217 bearings meet rigorous quality standards for reliable and long-lasting performance.
Part of our extensive range of Cylindrical Roller Bearings, the NJ 2217 is designed for separability. The inner ring with its roller and cage assembly can be mounted independently of the outer ring, which significantly simplifies the installation and maintenance processes, especially in tight or complex machinery. This feature, combined with its robust construction, makes the NJ 2217 a versatile and efficient solution for a wide array of heavy-duty machinery.
Features of the NJ 2217 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support much higher radial loads than ball bearings of the same size.
- Single-Direction Axial Location: The flange configuration provides axial location for the shaft in one direction, ensuring precise positioning.
- Separable Design: The inner and outer rings can be mounted separately, facilitating easier installation, inspection, and maintenance routines.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, enabling operation at high rotational speeds.
- Accommodates Axial Displacement: Allows for a certain degree of axial displacement of the shaft relative to the housing, compensating for thermal expansion.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and extended service life under harsh conditions.
Applications of NJ 2217 Bearings
- Industrial Gearboxes: Provides rigid support for gears and shafts, ensuring reliable power transmission.
- Pumps and Compressors: Used in heavy-duty pumps where high radial loads and operational reliability are critical.
- Electric Motors and Generators: Supports motor shafts, handling the significant radial forces generated during operation.
- Construction and Mining Equipment: Ideal for use in heavy machinery such as excavators, loaders, and crushers that operate in extreme environments.
- Rolling Mills: Supports the rollers in steel and metal processing plants, withstanding immense loads and high temperatures.
- Wind Turbines: Essential in the gearboxes and main shafts of wind turbines for efficient energy generation.
- Machine Tool Spindles: Offers the high rigidity and precision required for accurate machining operations.
Benefits of Using the NJ 2217 Bearing
- Enhanced Machine Reliability: Its high load-carrying capacity and robust design reduce the risk of premature failure, leading to less downtime.
- Simplified Assembly and Maintenance: The separable components make mounting and dismounting straightforward, saving time and labor costs.
- Improved Operational Efficiency: Low friction design minimizes energy loss and heat generation, contributing to smoother and more efficient machinery operation.
- Extended Service Life: High-quality materials and precision manufacturing ensure a long operational lifespan, even in demanding applications.
- Versatility in Application: Suitable for a wide range of heavy industrial equipment where both radial load support and axial guidance are needed.
- Compensates for Thermal Expansion: Its ability to manage axial displacement prevents stress buildup from temperature changes, protecting the bearing and associated components.
