    SHF gear units cross roller bearing installation


    1. Before installation, please clean bearing bracket, shaft, or other components,

    make sure there is no burrs or rough edge.


    2. Install the screws to connect crossed roller bearings with circular spline,

    then install the screws to connect bearings with flex spline.


    3. Install the wave generator and related components.
