Use oil HM32 ISO 3448 • Pressure range 8 - 80 bar Standard equipment Ordering example Double piston cylinder with shift ring Double piston cylinder ZHVD-SZ 068-17 Mounting screws or Stroke control on each cylinder Double piston cylinder ZHVD-SZ 068-17 Proximity bracket (without proximity switches) with rotary union (optional) Technical data ZHVD-SZ cylinder with retractable jaw chuck and power operated face driver Piston 2 for actuation of the driving pins in the face driver Piston 1 for actuation of the chuck and clamping jaws SMW-AUTOBLOK Type Id. No. Piston stroke mm Piston area A / piston force max. cm2 / kN Piston area B / piston force max. cm2 / kN Piston area C / piston force max. cm2 / kN Piston area D / piston force max. cm2 / kN Speed max. r.p.m. Weight kg Moment of inertia kg·m2 Operating pressure max. bar Operating pressure min. bar Oil leakage (*) dm3 / min Rotary union (option) Linear stroke control LPS 4.0 (option) * 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.
