Hydraulic supports are designed to support the workpieces in a specific plane and eliminate vibration during machining.
Support with single hydraulic supply port for extension and locking of the rod.
For the operating principle, consult the guide.
• screw fastening
• body with anti-corrosion treatment
• stainless steel spring
• prestress generated by spring
For operating pressure values below 150 bar, please enquire.
Special models can be made upon request.
