Definition

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.

Characteristics

• screw fastening
• rod treated to prevent seizing and corrosion
• stainless steel spring
• prestress generated by spring
• Supplied with O-rings:
5.28 x 1.78 – 90 NBR for AVBH 12 and AVBH22
7.65 x 1,78 – 90 NBR for AVBH 42

Optional

Special models available on request.
Please enquire for clamping pressure values below 150 bar.

Nota

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: 1.5l/min
