Heavy-Duty Pneumatic Clamping
Destaco’s WK400-120-6-1 Series of pneumatic power cylinders are the power elements of machines, tools, and other workholding devices.

WK400-200-6-A

Power element of machines, tool and devices. Mechanical advantage 10:1, due to the wedge lever principle. The unit has a two steps stroke consisting of the forward stroke and the power stroke with the amplified force (4 kN). Piston rod with ISO fit.
  • 10:1 mechanical advantage
  • Characteristic are the two steps of stroke: the forward stroke to move a certain distance and the power stroke with an amplified force on a short distance
  • Exact positioning of cylinder by flange mount on cylinder’s head
  • Cylinder works in any position
  • High durability because of solid and maintenance free wedge lever mechanics.
  • End position control by magnetic field sensing

Note: Operating pressure max. 6 bar [87psi], min 3 bar [44psi]. Use only clean, water- and oil-free compressed air. Piston rod is not secured against twisting and should not be loaded transversal.
