Double-Action Damping Cylinders 210 bar // series HZD4

General information

The HZD4 series cylinders are double-action pressure cylinders with end position damping that are universally applicable due to their various models and sealing variants. The damping is not adjustable. The piston rod guide is designed to be screwable for maintenance tasks. The piston rod consists of hightensile structural steel with an approximately 25µm hard chromium-plated layer. Other materials and coatings are available on request.

Please consult us in case of radial forces and non-vertical installation.
