Product Overview: The NUP 2217 Cylindrical Roller Bearing
The NUP 2217 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 85x150x36mm, this bearing is a key component in our Cylindrical Roller Bearings collection and a part of the versatile NUP 2200 Series. The NUP design is distinguished by its ability to provide axial location for a shaft in both directions, featuring two integral flanges on the outer ring and a single integral flange with a loose thrust collar on the inner ring. This makes it ideal for use as a locating bearing, accommodating both heavy radial loads and light axial loads with precision.
Manufactured to exacting standards, the NUP 2217 features a separable design, which simplifies the mounting and dismounting process as the inner ring can be handled independently of the outer ring and roller assembly. This bearing is designed for high-speed operation and offers exceptional rigidity and durability, making it a reliable choice for machinery where performance cannot be compromised.
Key Features of the NUP 2217 Bearing
- Bi-Directional Axial Location: Uniquely designed to locate the shaft axially in both directions, preventing unwanted movement.
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support very heavy radial loads.
- Separable Design: The inner ring can be mounted and dismounted separately, simplifying installation and maintenance procedures.
- High-Speed Capability: Engineered with low-friction characteristics, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-grade bearing steel for superior strength, durability, and a long operational lifespan.
- Enhanced Rigidity: Provides strong, rigid support to shafts, improving the overall stability and accuracy of the machinery.
Common Applications of NUP 2217 Bearings
