          Overview

          IBC NNU4964 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.
