The sealing system describes the designs and combinations of sealing elements in the Ratio-Clamp®.
For especially sensitive applications, the sealing system with a pressure piston seal can be used. In this system, the rod moves without pressurized seals when released.
Seal combination
Thus, the system's sliding friction is not influenced by the releasing pressure and will remain constant. This version is e.g. suitable for test applications.
Rod speed | up to 2 m/s |
Temperature range | from -30°C to +80°C |
Depending on the fluid used, the sealing materials need to be taken into account.
