• Thrust Ball Bearings

  • Thrust ball bearings provide optimum performance in high speed applications. Thrust ball bearings provide axial rigidity but are not recommended for applications experiencing any radial loads.

    Design Attributes
    Available in single direction and double direction designs
    Suitable for relatively high axial loads
    Low to medium speed ratings

    Minimum axial load
     It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways.
