Application:

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 high support forces already at 70 bar and can directly be connected to the low-pressure hydraulics of the machine tool. In case of the double-acting version, the return stroke of the support plunger is effected in a precisely defined time, that is above all advantageous in cycle-dependent installations.

Description:

The support plunger is hydraulically extended and retracted by means of a small double-acting cylinder. Contact to the workpiece is made by spring force. The pressure can be easily exchanged. Locking of the support plunger through the slotted clamping sleeve is made by means of a ringshaped conical hydraulic piston where the locking force is transmitted by a low-friction ball shell. Unlocking of the support plunger is made by spring force.
