B 1.7385 RS hydraulic slides 

The RS hydraulic slide is a compact hydraulic cylinder with 4 laterally-mounted guiding rods for compensation of high side loads and torques.
A stable front plate is mounted on the guide rods and the piston rod, enabling the various tools to be securely fastened.

The guide rods are made of high-tensile alloy steel and are chromium-plated. All other components are galvanized.
The front block made of St37k is not corrosion protected to facilitate machining.
