Sealing system pressure piston seal
Equipment of the Ratio-Clamp® clamping unit
The sealing system describes the designs and combination of the sealing elements within the Ratio-Clamp® clamping unit.
For particularly sensitive applications, the sealing system with pressure piston seal can be used. In this system, the rod moves without pressurized seals in the released state.
Seal combination
- Pressure piston seal
- Lip seal
- Wiper ring
The sliding friction of the system is therefore independent of the releasing pressure and constant. This version is suitable, for example, for test applications.
| Rod speed | up to 2 m/s |
