Product Overview: The NU 419 Cylindrical Roller Bearing
The NU 419 is a single-row cylindrical roller bearing engineered for superior performance in applications demanding high radial load capacity and high-speed operation. With dimensions of 95x240x55mm, this bearing is a key component in our NU 400 Series line of Cylindrical Roller Bearings. The 'NU' designation signifies a design with two integral flanges on the outer ring and a smooth, flangeless inner ring. This configuration allows the inner ring to be separated, which greatly simplifies the mounting and dismounting process, especially in tight-fit scenarios.
Designed to accommodate axial displacement of the shaft relative to the housing, the NU 419 is ideal for use as a non-locating bearing. Its line contact geometry between the rollers and raceways ensures excellent stress distribution, making it exceptionally reliable for supporting heavy radial forces in demanding industrial machinery.
Key Features of the NU 419 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support significantly higher radial loads than ball bearings of similar size.
- Separable Inner Ring Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation, inspection, and maintenance procedures.
- Axial Displacement Accommodation: Allows for thermal expansion or contraction of the shaft within the housing, preventing induced axial loads.
- High-Speed Performance: Engineered with precision geometry and surface finish to enable reliable operation at high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and extended service life.
- Low Friction: Optimized internal design minimizes friction and heat generation, contributing to operational efficiency.
Common Applications of NU 419 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, ensuring reliable power transmission under heavy loads.
- Large Electric Motors: Used to support motor shafts, handling the high radial forces generated during operation.
- Rolling Mills: Essential in the support rollers of steel and metal processing machinery where extreme loads are common.
- Construction and Mining Equipment: Deployed in heavy machinery like excavators, crushers, and conveyors for its durability and load-bearing capabilities.
- Pumps and Compressors: Ensures stable rotation of shafts in industrial pumping and compression systems.
- Vibrating Screens: Withstands the intense vibrations and heavy loads characteristic of screening and sorting equipment.
- Wind Turbines: Utilized in gearbox and main shaft applications to manage significant radial forces.
Benefits of Using the NU 419 Bearing
