Application:

Single-acting block cylinders can be used for all hydraulically-operated linear movements that do not require a retraction force or where the piston is retracted by an external force.

Function:

With spring return

When pressurising the cylinder the piston extends. After pressure relief, the piston is retracted by spring force. The pressure spring must not only overcome the friction forces, but must also supply the hydraulic oil back to the reservoir.

Without spring return

When pressurising the cylinder the piston extends. After pressure relief, the piston must be retracted by an external force. Since no pressure spring is installed, this single-acting block cylinder has the same stroke as the double acting version with the same length.
