Product Overview: The NU 2216 Cylindrical Roller Bearing
The NU 2216 is a high-capacity single-row cylindrical roller bearing with principal dimensions of 80x140x33mm. As a key component in our Cylindrical Roller Bearings range and part of the NU 2200 Series, this bearing is engineered to handle substantial radial loads at high speeds. Its distinct NU design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured from premium-grade bearing steel, the NU 2216 offers exceptional durability and operational reliability. The line contact between the rollers and raceways provides high stiffness and is perfect for applications in heavy industrial machinery where precision and strength are paramount.
Key Features of the NU 2216 Bearing
- High Radial Load Capacity: The cylindrical roller design with line contact ensures excellent distribution of heavy radial forces.
- Accommodates Axial Displacement: The NU design with a flangeless outer ring allows for thermal expansion or contraction of the shaft.
- Separable Design: The inner ring with its roller and cage assembly can be mounted independently of the outer ring, simplifying installation and maintenance.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high-speed rotational applications.
- Robust and Durable: Constructed from high-purity, hardened bearing steel for extended service life and resistance to wear.
- High Stiffness: Provides rigid support for shafts, minimizing deflection under heavy loads.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts in transmission systems.
- Large Electric Motors: Used as non-locating bearings to support motor shafts and accommodate thermal growth.
- Pumps and Compressors: Ensures reliable operation in high-load industrial fluid and gas handling equipment.
- Construction and Mining Equipment: Ideal for heavy machinery such as excavators, cranes, and crushers.
- Rolling Mills: Withstands the extreme radial loads found in steel and metal processing applications.
- Machine Tool Spindles: Offers the rigidity required for precision cutting and milling operations.
- Vibrating Screens and Shakers: Capable of handling the heavy, shock-like radial loads typical in aggregate and material processing.
Benefits of Using the NU 2216 Bearing
- Enhanced Machine Reliability: High load capacity and robust design reduce the risk of premature bearing failure and machine downtime.
- Simplified Assembly and Disassembly: The separable nature of the bearing makes mounting and inspection straightforward.
- Improved Operational Efficiency: Low-friction design minimizes power loss and heat generation, contributing to energy savings.
- Extended Service Life: Superior materials and manufacturing precision result in a longer operational lifespan, reducing total cost of ownership.
- Versatility in Application: Suitable for a wide range of heavy-duty industrial environments where high radial loads are present.
- Compensation for Misalignment: While primarily for radial loads, it can tolerate minor axial shifts, preventing stress on the system.
