In "return", there are cylinders that return by self-weight or self-weight and cylinders that return by spring force. The return spring has only the force needed to reset the piston. If a heavy fixture is mounted on the piston and used, it may not return. Also, the return time is not constant due to the length of the hose.
As a standard product, we produce 40kN (4tonf) to 700kN (70tonf) with a stroke of 15mm to 500mm. We also design and manufacture specially designed cylinders.
