NUP 312 N FAG Cylindrical Roller Bearing 60x130x31

Cylindrical Roller Bearing for High Radial Loads

NUP Design for Axial Location in Both Directions

Reliable Solution for Heavy Industrial Applications

Main Description

NUP 312 N FAG is a single row cylindrical roller bearing with dimensions 60x130x31, designed for demanding industrial applications where very high radial load capacity and secure axial shaft location are required. Thanks to its NUP construction, this bearing can act as a locating bearing, providing axial guidance of the shaft in both directions without additional locating components.

The bearing design includes two fixed flanges on the outer ring, one fixed flange on the inner ring, and an additional N locating ring mounted on the inner ring. This configuration enables the bearing to carry high radial loads while simultaneously transmitting limited axial loads in both directions. As a result, the entire bearing unit operates with excellent stability and predictable behavior under heavy operating conditions.

Compared to a standard ball bearing, the cylindrical roller design offers significantly higher radial load capacity, which translates into high durability and extended service life in continuous operation. When correctly mounted in a suitable bearing housing, NUP 312 N FAG reduces vibration, limits wear of cooperating components, and supports reliable machine performance.

This bearing is commonly used in industrial gearboxes, electric motors, production machinery, heavy drive systems, and mechanical assemblies where precise axial positioning of the shaft is essential. It is widely selected by OEM manufacturers, maintenance departments, and industrial service providers who require robust components with clearly defined technical parameters.

FAQ - Frequently Asked Questions

What is an NUP 312 N cylindrical roller bearing?
It is a single row cylindrical roller bearing that provides axial location of the shaft in both directions.
