TuffGrip High Capacity Fluid Advance 4-Bolt Base Inch Hydraulic Work Supports

Now up to 3X competitive capacity at 5,000 PSI!

Plungers stay retracted during part loading. Hydraulic pressure advances the plunger exerting only spring force as it makes contact with the part. Hydraulic pressure then automatically sequences, “freezing” the plunger, to properly support the part.

Available in 1000, 2000, 4000 & 8000 lb. capacity.
Used units are fully factory refurbishable to like new condition if the support body is undamaged.
Ventless configuration and built in wipers protect the plunger movement from chips and debris.
Four bolt base is compatible with Vektek In-Port flow control and In-Port sequence valves.
Uses Vektek’s BHC technology to guard against corrosion.
O-ring face seal design makes machining cavities easier.

Standard SAE porting and alternate o-ring manifold face seal is located in the base of the support for bolt down installation. The base can be removed for direct cartridge mounting.

NOTE: The maximum system back-pressure a fluid advance work support can overcome is 10 psi. Returning back-pressure greater than 10 psi may cause slow or failed retraction.

High Capacity Fluid Advance Base Mount Workholding

TuffGrip High Capacity Fluid Advance Work Support - Capacity Workholding

* Support capacities are listed at 5,000 psi maximum pressure. Support capacities for other pressures are shown in the fluid advance High Capacity and Part Present Sensing load capacity chart.
** Restrict flow rate to a maximum of 130 cu. in./minute.
*** For cartridge mount models, see cavity dimensions drawings in this catalog section.
**** In-Port Valves require the use of manifold mount ports

For proper sealing, all mating surfaces should be flat within 0.003 inches, with a maximum surface roughness of 63 μ in. R_a. Hydraulic oil feed holes for manifold mounting Ø 0.09 to Ø 0.20 inches.
