CST, CDT-Series, Threaded Cylinders

Enerpac threaded cylinder body allows for fine positioning and easy installation
Minimum cylinder diameter combined with maximized clamping forces
Nitro carburized bodies and internal plunger wipers allow maintenance-free, high cycle performance
Center-tapped plunger will hold workpiece contact buttons
Single-acting cylinder models with spring return simplify hydraulic tubing requirements
Double-acting cylinder models are ideal for applications requir powered pulling toward the cylinder body
