Easily accessible lifting spring

Varying conditions may require a different rate lift spring. An extended head cap may require a heavier spring, due to the added weight. A lighter spring may help prevent deflection on thin section work-pieces.

Viton seal design

Fluorine rubber (Viton) is used for the plunger scraper as will as the pressure seals. Viton is compatible with chlorine based cutting fluids and coolants.

Stainless steel parts

Plunger, sleeve, head cap and springs are made of stainless steel for longer life.

Air cleaning circuit

The standard-equipped vent can be used as an air cleaning circuit. When the work support is not under pressure, air can be used to clean the gap between the sleeve and plunger. This helps prevent the intrusion of high-pressure coolant or chips.

Optional lower flange

Flexible mounting with threaded port or manifold connections.
