Product Overview: The NUP 317 Cylindrical Roller Bearing
The NUP 317 is a single-row cylindrical roller bearing designed for high-performance industrial applications. With principal dimensions of 85x180x41mm, this bearing is part of our extensive Cylindrical Roller Bearings range. The NUP designation signifies a unique design with two integral flanges on the outer ring and one integral flange plus a loose flange ring on the inner ring. This configuration allows the bearing to locate the shaft axially in both directions, making it an excellent choice for applications requiring precise shaft guidance under heavy radial loads.
Manufactured to stringent industry standards, the NUP 317 offers high stiffness, low friction, and is suitable for high-speed operation. Its separable design—where the inner ring, outer ring, and roller/cage assembly can be mounted independently—greatly simplifies installation and maintenance procedures. As a trusted supplier, we provide robust bearings like the NUP 317 to ensure the reliability and longevity of your machinery. Explore our full range of NUP Series bearings to find the perfect component for your needs.
