Specifications

Work Support Capacity to be equal
or greater than 1.5 times clamping
force plus machining force.

Fluid Advance Work Supports hydraulic pressure pushes a spring which lifts plunger, hydraulic pressure locks in place.

For proper sealing, the mating surface must be flat within 0.08 mm with a maximum 1.6 µm R surface finish.

Optional in-port flow
control is a meter-in
device with reverse
free flow check valve.

WARNING! Operating above 7 MPa may damage the work support and will void warranty.

*Support capacities are listed at 7 MPa (70 bar) maximum pressure.
Support capacities for other pressures are shown on the Capacity Charts.

** "P" in the formula is hydraulic pressure measured in MPa.

*** To allow for work piece height variations, it is recommended that the plunger contacts the part at Mid-Stroke.

**** Set plunger lifting time to 0.5 seconds, or longer, by adjusting the flow control valve.
Use a flow control valve with cracking pressure of 0.1 MPa or less. In-port flow control requires the use of manifold mount ports.

Features

Fluid Advance Top Flange Features

Available in three capacities:
5.5kN, 10kN, 16 kN, 26kN.
Normally retracted plungers do not interfere with part loading. Advance them with hydraulic pressure, exerting only spring force when contacting your part. Hydraulic pressure then automatically sequences, "freezing" the plunger
properly against the part.
Choose between a High-Tension
or Low-Tension spring to fit
your application.
Top Flange minimizes the distance from mounting surface to the part for compact and efficient design.
Plumb through BSPP ports or
manifold mount.
Minimal friction wiper design keeps chips and debris out while providing smooth plunger action.
Optional in-port flow control available for this model.

Bearing grade stainless steel plunger and collet assembly helps guard against corrosion in most machining environments.

The maximum system back-pressure
a fluid advance work support can
overcome is 0.07 MPa (0.7 bar).
Return back-pressure greater than
0.07 MPa (0.7 bar) may cause
slow or failed retraction.
