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. The selectable extension with a shaft diameter of only 16 mm enables the support of surfaces in recesses and cavities that otherwise would be inaccessible.
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 single or double-acting cylinder. Contact to the workpiece is made by spring force. The pressure spring can be easily exchanged. The support plunger is additionally guided in the area of the shaft diameter and can therefore absorb side loads up to 300 N.
