DCE
■ Double piston rotating hydraulic cylinder ■ Up to 70 bar ■ Central bore for air / coolant / oil ■ Stroke control via proximity switch or LPS 4.0 Application/customer benefits • Actuation of 2 + 2 power chucks type TPT with 2 piston actuation • Actuation of power chuck with part ejector • Actuation of power chucks with retractable axial stop / finger chucks with power operated centering fixture Technical features • Double piston cylinder with 4 way oil manifold for separate actuation of the 2 cylinders • Pressure range 8 - 70 bar • Horizontal or vertical installation • Safety valves on the biggest cylinders and stroke control on each cylinder (piston 1) • Central bore for air, coolant or oil with thread for rotary union
Equal piston area and stroke 2 independent pistons
• Mounting from the rear side with bolts • A 10 μm filter in pressure line is requested • Use oil HM32 ISO 3448 Standard equipment Double piston cylinder with switch ring

Oil leakage (*)
dm 3 /min
* Total at 30 bar / 50 °C. Important: On higher pressure the leakage increases proportionally. On higher oil temperature the leakage increases over proportionally (the use of an oil cooler is recommended). When designing / checking the hydraulic unit please ask for our data sheets.
