Overview
FAG NNU4952-S-K-M-SP 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.
