Work support with screw cartridge – 500 bar – hydraulic extension AVCV
Cartridge type
Locking force at 500 bar: 16 to 102 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.
• direct supply through manifold block
• rod treated to prevent seizing and corrosion
• stainless steel spring
• supplied with O-rings and anti-extrusion ring.
For operating pressure values below 150 bar, please enquire
IMPORTANT
The bleeder must always be located at the highest point in the fixture.
In order to allow the rod to be retracted by springs, the counter pressure must not exceed 2 bar.
Maximum flow rate: 1.5 l/min
