Product Overview: The NU 216 Cylindrical Roller Bearing
The NU 216 is a high-performance single-row cylindrical roller bearing, engineered to handle heavy radial loads and high speeds. With precise dimensions of 80x140x26mm, this bearing is a crucial component in demanding industrial applications. As a key part of our NU 200 Series, it features a separable design where the inner ring is free of flanges, allowing it to be mounted separately from the outer ring and roller assembly. This unique characteristic enables the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion.
As a specialist supplier of industrial components, we ensure every NU 216 bearing meets stringent quality standards. It is an indispensable part of our broader Cylindrical Roller Bearings collection, designed for superior reliability and service life. The line contact between the rollers and raceways minimizes stress concentrations, allowing for greater rigidity and load-bearing capacity compared to ball bearings of similar dimensions.
Key Features of the NU 216 Bearing
- Separable Design: The inner ring can be mounted independently of the outer ring and roller cage, simplifying installation and maintenance.
- High Radial Load Capacity: Engineered with cylindrical rollers to support heavy radial forces, making it suitable for demanding machinery.
- Axial Displacement Accommodation: The flangeless inner ring design allows for axial movement of the shaft, compensating for thermal expansion or mounting inaccuracies.
- Low Friction and High Speed: Optimized internal geometry reduces friction and heat generation, enabling efficient operation at high rotational speeds.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- Interchangeability: Produced to standard ISO dimensions, ensuring it can be easily interchanged with other manufacturers' equivalent bearings.
Common Applications for NU 216 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in power transmission systems.
- Electric Motors: Used as non-locating bearings to support motor shafts, allowing for thermal growth without inducing stress.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors operating under heavy loads.
- Construction Machinery: Essential for equipment such as excavators and cranes, where durability and high load capacity are critical.
- Vibrating Screens and Crushers: Withstands the heavy loads and vibrations found in mining and aggregate processing equipment.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed cutting and grinding applications.
- Rolling Mills: Used extensively in steel and metal processing to support the rollers that shape raw materials under extreme pressure.
Benefits of Using the NU 216 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads and axial displacement reduces stress on the shaft and other components, minimizing downtime.
- Simplified Assembly and Maintenance: The separable nature of the bearing allows for easier mounting and dismounting, saving time and labor costs.
- Longer Service Life: The durable materials and low-friction design contribute to an extended operational lifespan, even in harsh environments.
- Improved Operational Efficiency: Minimizes energy loss through friction, contributing to more efficient and cost-effective machinery performance.
- Versatile Performance: Suitable for a wide range of industrial applications, offering a reliable solution for non-locating bearing positions.
- Prevents Thermal Stress: Effectively manages shaft expansion and contraction, preventing premature bearing failure and damage to machinery.
