Product Overview: The NU 405 Cylindrical Roller Bearing
The NU 405 Cylindrical Roller Bearing is a high-capacity, single-row bearing engineered for demanding industrial applications. With key dimensions of 25mm bore diameter, 80mm outer diameter, and 21mm thickness, this bearing is part of the robust NU 400 Series. Its design, a key feature of the NU Series, consists of an inner ring without flanges and an outer ring with two integral flanges. 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.
As a specialist supplier of Cylindrical Roller Bearings, we guarantee that the NU 405 is manufactured to precise industry standards. The line contact between the rollers and raceways provides high radial load-carrying capacity and high stiffness, ensuring reliable performance under heavy loads and at high speeds.
Key Features of the NU 405 Bearing
- Axial Displacement: The flangeless inner ring allows for axial movement of the shaft, compensating for thermal expansion or mounting inaccuracies.
- High Radial Load Capacity: Engineered with a single row of cylindrical rollers, providing excellent capacity for heavy radial forces.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- High Stiffness: The line contact geometry between rollers and raceways results in high radial stiffness, essential for precision applications.
- High-Speed Capability: Designed for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and extended operational life.
Common Applications of NU 405 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling heavy radial loads common in power transmission.
- Electric Motors: Used as non-locating bearings on motor shafts to allow for thermal expansion during operation.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps where high radial forces are present.
- Machine Tool Spindles: Offers the high stiffness required for precision and rigidity in milling and turning machines.
