    Description
    B 1.9470 Threaded-Body Work Supports

    Hydraulic work supports are used to provide a self-adjusting rest for workpieces and avoid their vibration and deflection under machining loads.
    This series offers very high support forces already at 70 bar and can directly be connected to the low-pressure hydraulic of the machine tool.

    The support plunger is hydraulically extended by a small piston and contacts the workpiece with spring force. The pressure spring can be easily exchanged.
    Locking of the support plunger through the slotted clamping sleeve is made by means of a ring-shaped conical hydraulic piston where the locking force is transmitted by a low-friction ball shell. Unlocking and retracting of the support plunger is made by spring force.
