Vektek Low Pressure 7MPa Catalog

7 MPa Work Supports

Fluid Advance Cartridge Work Support

Retracted Plunger Applications n Available in four capacities ranging from 3.0 kN to 10 kN. n Normally retracted plungers do not interfere with part loading. Advance them with hydraulic pressure, exerting only spring force to bring plunger into contact with the part. Hydraulic pressure then automatically sequences, “freezing” the plunger properly against the part. n Choose between a High-Tension or Low-Tension Spring to fit your application. n Floating locator that doesn't interfere with 3-2-1 locating principles. n Only spring force is applied to the part. Hydraulic actuation freezes the plunger without exerting any additional force on the part. n Minimal friction wiper design keeps chips and debris out while providing smooth plunger action. n Cartridge style work supports provide designers with additional mounting options. These supports can be thread mounted into a fixture or custom cavity mounted.


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

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

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 at the start of Section B. Operating work supports above maximum pressure may damage work support and void warranty. ** "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.

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

NOTE: 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.
