Product Overview: The NUP 218 Cylindrical Roller Bearing
The NUP 218 is a high-capacity single row cylindrical roller bearing, engineered to handle heavy radial loads and provide axial location for shafts in both directions. With principal dimensions of 90x160x30mm, this bearing is a crucial component in demanding industrial applications. As part of our extensive NUP Series, it features two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring. This unique configuration allows it to function as a locating bearing, securing the shaft against axial movement.
Manufactured to precision standards, the NUP 218 bearing offers a separable design, meaning the inner ring with its roller and cage assembly can be mounted independently from the outer ring. This simplifies installation, inspection, and maintenance procedures. As a trusted supplier of cylindrical roller bearings, we provide components that ensure reliability, efficiency, and longevity in various types of machinery.
Key Features of the NUP 218 Bearing
- Bi-Directional Axial Location: Its specific flange design allows it to locate the shaft axially in both directions, making it ideal as a fixed-end bearing.
- High Radial Load Capacity: The line contact between the rollers and raceways enables the bearing to support heavy radial loads.
- Separable Design: The inner and outer rings can be mounted separately, simplifying the assembly and disassembly process.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, it is suitable for applications involving high rotational speeds.
- Durable Construction: Made from high-purity, hardened bearing steel for exceptional durability and resistance to wear.
- Interchangeability: Produced to standardized dimensions, ensuring it is interchangeable with other manufacturers' NUP 218 bearings.
