Product Overview: The NU 318 Cylindrical Roller Bearing
The NU 318 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With key dimensions of 90mm bore diameter, 190mm outer diameter, and 43mm thickness, this bearing is a crucial component in our Cylindrical Roller Bearings collection. Part of the robust NU 300 Series, the NU 318 features a unique design where the inner ring is separable and has no flanges, while the outer ring has two integral flanges. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an ideal non-locating bearing.
Manufactured to precise industry standards, the NU 318 is engineered to handle heavy radial loads at high speeds. Its separable design simplifies the mounting and dismounting process, which is particularly advantageous for applications requiring frequent maintenance or tight-fit installations. Trust our expertise as a leading supplier to provide reliable and durable mechanical parts for your machinery.
Key Features of the NU 318 Bearing
- Separable Inner Ring: Allows for easier and more convenient installation and maintenance, as the inner and outer rings can be mounted independently.
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The flangeless inner ring design allows for axial movement of the shaft, compensating for thermal expansion or mounting inaccuracies.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-rotational speed applications.
- Robust Construction: Made from high-quality bearing steel to ensure durability, reliability, and a long service life under tough operating conditions.
- Interchangeability: Manufactured to standard dimensions, ensuring it can be easily interchanged with other equivalent bearings.
Common Applications for NU 318 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy radial loads common in gear systems.
- Electric Motors: Used as non-locating bearings on motor shafts to support radial loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures reliable operation of rotating components in various types of industrial pumps and compressors.
- Construction and Mining Equipment: Ideal for heavy machinery like excavators, loaders, and crushers where durability is critical.
