Work support with cartridge – 300 bar AVC
Cartridge type
Locking force at 300 bar: 5 to 20 kN
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.
Examples of fixtures, see at the bottom of the page.
• fastened by upper flange
• direct supply through manifold block
• stainless steel return spring
For operating pressure values below
150 bar, please enquire.
Special models can be made upon request.
IMPORTANT
The bleeder must be located at the highest point in the fixture.
In order to allow spring return, the counter pressure must not exceed 2 bar
Max flow rate: 1.5 l/min
