Work Supports / Double Acting
Features and Capacity
All Double Acting Work Supports styles are available in 2,750 lbs and 5,500 lbs capacities at 5,000 psi. Exclusive Vektek design eliminates part ejection of any workpiece and the need for ancillary part retention devices. Innovative design features a spring advanced work support within a double-acting shuttle cylinder. A wiper at the shuttle and at the plunger keep chips out and your work support running smoothly. Double Acting Work Supports sleeve design is 2.5 times thicker than other work support models on the market. This sleeve efficiently closes and uniformly grips the plunger making it superior in precision applications. BHC™ (Black Hard Coat) body, hardened chrome shuttle piston and stainless steel plunger promote long life in harsh machining environments. The Position Sensing option is an aluminum housing that is Black Anodized for corrosion resistance. Double Acting Work Support Features

Input Pressure (psi)
Double Acting Work Support Operation Advance: Hydraulic pressure extends the shuttle cylinder to the full stroke position, moving the work support plunger to the part. The spring advanced plunger will contact the part during the shuttle extension applying only spring force. Internal sequencing occurs after the shuttle is fully extended allowing hydraulic pressure to lock the plunger inside the sleeve. Retract: The sleeve maintains its locked condition while hydraulic pressure retracts the shuttle. On reaching the full retracted position, the sleeve unclamps and the plunger returns to its spring advance state at least 0.125 inches below the part (may be separated from the part by as much as 0.50 inches).
