Single-Action Hydraulic Cylinder for Scissor Lift Tables up to 210 bar // HZE1
General Information
The cylinders in the HZE1 series are single-acting pressure cylinders that can be used universally thanks to their different designs and sealing variants. The piston rod guide can be screwed for maintenance purposes. The piston rod is made of high-strength structural steel with a hard chrome coating of approx. 25μm. Other materials and coatings are available on request. The piston rod end is guided in the cylinder tube, which minimizes wear on the piston rod guide and the seal. For lateral forces and non-vertical installation, please contact us.

Connecting Bore
The connection hole is located at the bottom end of the cylinder and is designed for line break valves.
The position on the circumference can be changed (standard P8).

For long strokes, the support width of the piston rod in the cylinder tube can be changed in order to reduce the load on the guide system when fully extended. This also depends on the type of installation and the design of the cylinder.
