CKN Servocylinder (magnetostrictive)

Subplates

Incorporated subplates allow the direct mounting of the valves on the cylinder. For strokes shorter than 150 mm, the cylinder will be provided with suitable spacers.

Stroke (mm)

The stroke is the maximum displacement of the piston rod. Specify the desired stroke entering the value in the field provided

Please select a value between the range

Select a value between 100 and 4000 with step 100 and confirm to continue

Mounting style

For mounting style L and strokes shorter than 35 mm, the configured cylinder is automatically equipped with a spacer, minimum length 50 mm. Spacers length selection will be available in subsequent configuration steps.

Cushionings

Cushionings’ profiles are designed to reduce the cylinder speed before the rod contacts the mechanical stroke-end, dissipating the energy with limited pressure spikes. These hydraulic dampers also reduce mechanical shocks. The adjustable versions are equipped with cartridge valves to increase max damping energy extracted from cushionings chart in table B015 (section 7.5) or to optimize the cushioning performances in different applications.

Spacers

The spacers increase the rod and piston guide to protect them from overloads and premature wear, they are recommended for strokes longer than 1000 mm in pushing working condition.
The overall dimension of the cylinder increases by a value equal to the length of the spacers.
For strokes longer than 3000 mm is recommended to contact our technical office.
Spacers are mandatory for strokes shorter than the minimum values for subplates and for mounting style “L”.
