• 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
