        Overview

        INA 81228 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.
