VH = work stroke, RH = back stroke

Design:

Cylinder barrel from steel, hardened and burnished. Piston and piston rod case hardened and ground. Piston rod with through-hole and internal thread. Wiper at piston rod. Return spring from stainless steel. Oil supply via threaded port.

Application:

Particularely suitable to retrofit existing mechanical fixtures for hydraulic actuation. The hollow cylinder can be operated as push or pull cylinder. Universal cylinder for clamping, pushing, locking and punching.

Features:

Clamping cylinder with tapped piston rod. Tapped piston rod ends allow the use of custom end attachments.

Note:

For single acting cylinders there is the risk of succing in coolant through the breather port. Therefore, the sinter metal breather has to be protected e.g. by cover plates from direct access of coolant. The system has to be completely vented thoroughly during installation.
