Available with application-specific customisation for torque range, material protection, and corrosion resistance

Features and Advantages

The FKH hydraulic flange coupling provides a rigid, backlash-free connection between two shafts, such as between a motor and gearbox. The coupling uses a conical hydraulic system to generate radial pressure that securely clamps the shaft surfaces. Once the coupling is locked mechanically, the hydraulic pressure is released, maintaining a strong frictional connection. Its compact, single-cone construction requires minimal installation space and allows fast tightening and loosening, making it ideal for shafts requiring frequent assembly or high torque transfer.

In combination, the TAS Schäfer FKH and WHS hydraulic coupling systems deliver a safe, maintenance-friendly, and repeatable method of achieving secure, high-torque shaft and hub connections in precision drive applications such as marine, wind energy, and process machinery.

Typical Applications

Hydraulic couplings are widely used across industries where precision, safety, and repeatability are essential.
Common examples include:

Drive technology and test benches

Gearbox-to-shaft couplings

Wind energy systems

Hydraulic motor drives

Conveyor and heavy-duty power transmission equipment
