Hydropower technology
Your expert for frictional connections
TAS SCHÄFER GmbH is a leading supplier of high-precision frictional connections and coupling systems for industrial applications. With decades of experience and technological expertise, the company develops customised solutions for various industries, including wind energy, mechanical engineering and heavy industry.
A reliable connection
In modern hydroelectric power technology, precise and reliable mechanical connections play a crucial role. Our highly specialised connection flanges, shrink discs, shaft couplings, flange couplings and locking devices are used in hydroelectric power plants to maximise the efficiency and longevity of the plants.

Use of shrink discs in hydroelectric power plants
Shrink discs provide a backlash-free and high-strength connection between shafts and hubs, making them ideal for the demanding requirements of hydroelectric power plants. They are mainly used to connect generator shafts and turbine shafts. The ease of assembly and disassembly, as well as the ability to transmit high torques, make shrink discs a preferred choice in hydroelectric power engineering.
Shaft couplings and flange couplings in hydroelectric power
Shaft couplings and flange couplings are indispensable components for the reliable transmission of torque and power in hydroelectric power plants. Our flange couplings are specially designed for use in hydroelectric power plants and ensure precise alignment and a secure connection between different plant components, such as turbines and generators.
Use of locking assemblies in Francis turbines
Our locking assemblies are used in hydroelectric power technology, particularly in Francis turbines. This type of turbine places high demands on the connecting mechanisms due to the complex loads and high speeds. Stainless locking assemblies are particularly important here to ensure corrosion resistance and a long service life.
The importance of stainless steel designs
In hydroelectric power engineering, the corrosion resistance of the connecting elements used is of crucial importance. Our stainless steel shrink discs, shaft couplings, flange couplings and locking assemblies provide optimum protection against corrosion, reducing maintenance costs and increasing the service life of the equipment.
Advantages and applications
Simultaneous transmission of multiple loads such as torsional and bending moments, axial or lateral forces
Easy assembly and disassembly through backlash-free joining of shaft and hub
Splash-free shaft-hub connection. Hub can be positioned in both the direction of rotation and the axial direction
Insensitive to shocks and impacts in the drive train
Frequently asked questions
What is the significance of the material's yield point for the design?
For the TAS Schäfer GmbH team, knowledge of the yield strength is crucial to ensure that components do not suffer permanent deformation under the expected loads. It serves as a basis for calculating safety factors and selecting suitable materials for the specific applications.
Where can I find the relevant assembly instructions for the products?
You can find the assembly instructions for all TAS Schäfer GmbH products on the homepage in the ‘Downloads’ section. Of course, our sales and design staff are always available to answer any questions you may have.
What should be considered if the shaft diameter differs from the catalogue specification?
For deviations, you will find an overview of the permissible deviations on the respective catalogue pages of the individual series. For deviations that go beyond this, the design department of TAS Schäfer GmbH should be consulted. The influence on the transmissible torque can be calculated as follows:
