CY, HCS, QDH, RWH-series, Hollow plunger cylinders

CY, HCS, QDH, RWH series, Hollow plunger cylinders
  • Enerpac hollow plunger cylinders provide high force push & pull applications on and around the fixture
  • Load can be attached to either end of the cylinder, providing a choice of push or pull actions – both realizing full cylinder capacity
  • Very high cylinder capacities contained within small dimensions allow compact fixture designs
  • Spring return operation allows for easy unloading of the workpiece
  • Threaded collars and base mounting holes allow mounting flexibility, including table-top surfaces and T-slots
  • Nickel-plated hollow plungers, plunger wipers and internal venting prevent corrosion and support longer operation life on all HCS models
