Product Overview: The NU 2316 Cylindrical Roller Bearing
The NU 2316 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With dimensions of 80mm bore diameter, 170mm outer diameter, and 58mm thickness, this bearing is engineered to handle heavy radial loads at high speeds. As a key component in our Cylindrical Roller Bearings range, the NU 2316 is part of the robust NU 2300 Series. Its 'NU' design features two integral flanges on the outer ring and a flangeless inner ring, allowing it to accommodate axial displacement of the shaft relative to the housing in both directions. This makes it an excellent choice for non-locating bearing positions, particularly where thermal expansion of the shaft is a factor.
Key Features of the NU 2316 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent radial stiffness and allows for the support of heavy loads.
- Accommodates Axial Displacement: The NU design permits the shaft to move axially in either direction relative to the housing, preventing induced axial loads from thermal expansion.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation, inspection, and maintenance procedures.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, this bearing is well-suited for high rotational speed applications.
- Robust Construction: Manufactured from premium, high-purity bearing steel for superior durability, wear resistance, and extended operational life.
- Logarithmic Roller Profile: Reduces edge stresses at the roller/raceway contact, increasing reliability under heavy loads and minor misalignments.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, ensuring reliable power transmission under heavy loads.
- Electric Motors: Used as a non-locating bearing to support motor shafts, accommodating thermal growth during operation.
- Pumps and Compressors: Ensures smooth and efficient rotation of shafts in various industrial pumping and compression equipment.
- Construction Machinery: Ideal for heavy-duty equipment like excavators, cranes, and road rollers where high radial forces are common.
- Rolling Mills: Withstands the extreme loads and high speeds found in steel and metal processing machinery.
- Vibrating Screens and Crushers: Offers the durability needed to operate reliably in high-vibration environments like mining and aggregate processing.
- Wind Turbines: Used in gearboxes and main shafts to manage the significant radial forces generated by the rotor.
Benefits of Using the NU 2316 Bearing
- Enhanced Machine Reliability: High load capacity and robust design reduce the risk of premature failure, minimizing downtime.
- Simplified Assembly and Maintenance: The separable nature of the bearing allows for easier and faster mounting and dismounting.
- Improved Operational Efficiency: Low-friction design minimizes energy loss and heat generation, contributing to more efficient machinery.
- Extended Service Life: Superior materials and design features like the logarithmic profile reduce wear and extend the bearing's lifespan.
- Versatile Application: Its ability to handle axial displacement makes it a versatile solution for a wide range of non-locating bearing arrangements.
- Prevents Thermal Stress: By allowing for shaft expansion, the bearing protects itself and other machine components from damaging axial loads.
