    Description
    B 1.942 Threaded-Body Work Support

    Hydraulic work supports are used to provide a self-adjusting rest for the workpiece during the machining operations. They compensate the workpiece surface irregularities, also vibration and deflection under machining loads.
    The threaded-body design allows for space-saving and direct installation into the fixture body. Oil supply is made through drilled channels.

    In the body of the threaded-body work support a thin-walled locking bush is integrated, which locks cylindrically around the freely-movable support plunger when pressurising the element with hydraulic oil.

    For contact of the support plunger at the workpiece there are 3 possibilities:

    • Spring force
    • Air pressure advanced
    • Oil pressure combined with spring force

    The elements are protected against penetration of swarf by a metallic wiper edge and sealed against liquids. The venting port allows also the connection of air sealing. A mounting body for pipe threads or drilled channels is available as accessory.
