Overview

FAG NU308-E-XL-M1 Cylindrical Roller Bearing is designed for high radial load capacity through line contact between rollers and raceways. It is suitable for rigid, heavy-duty applications such as motors, gearboxes, rolling mills, and machine tools, with N, NU, NJ, and NUP designs offering different axial locating functions.

Cylindrical rollers and a cage are arranged between inner and outer ring raceways. Depending on flange configuration, the bearing can be separable and may support axial load in one or both directions.

Key features

High radial load capacity
Rigid performance for high-speed operation
Separable design for easier mounting
Axial locating capability by design variant

Typical applications

Industrial electric motors
Gearboxes and reducers
Machine tool spindle support positions
Rolling mills, paper machines, and heavy machinery

Selection guidance

Choose the N, NU, NJ, or NUP design by load direction, axial locating requirement, cage material, internal clearance, and lubrication condition.
