Hydraulic clamping device Ratio-Clamp®
Hydraulic rod clamping device and locking unit from Hänchen

The patented hydraulic clamping device Ratio-Clamp® hold the rod in a standstill and locks it into position mechanically. The clamping effect is immediate, lasts for an unlimited period of time and doesn't require an energy supply – suitable for various applications, as a safety element or for locking component parts into place. 100% reliable!
Rod clamping device Ratio-Clamp® hold the rod in a standstill and locks it into position mechanically.
Hydraulic rod clamps for sensitive applications
Locking unit with sealing system pressure piston seal
For very sensitive applications, we recommend the design with pressure piston seal, where no pressurized seal is touching the rod. Thus, the sliding friction is very low and remains constant regardless of the releasing pressure.
