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
Extracting raw materials requires robust and reliable connections between machine components. Shrink discs and flange couplings play a crucial role here. Shrink discs provide a backlash-free, force-locked connection that transmits high torques and axial forces. They are ideal for applications where high loads and vibrations occur.

Flange couplings perfectly complement shrink discs by creating flexible yet strong connections between rotating shafts. These couplings are easy to assemble and disassemble, making maintenance and replacement easier. In raw material extraction, they ensure the necessary stability and efficiency.
The combination of shrink discs and flange couplings optimises machine performance, minimises downtime and extends the service life of components. These connecting elements are made of high-strength materials that function reliably even under extreme conditions.
Use of flange couplings in the raw materials industry
- Secure connection: Flange couplings ensure a secure and firm connection between different machine parts, such as pumps, engines and conveyor systems. They are designed to absorb high loads and vibrations.
- Flexibility: Flange couplings make it easy to replace or maintain machine components. This increases the flexibility and adaptability of the systems to different operating requirements.
- Efficient power transmission: Flange couplings provide efficient power transmission and minimise energy loss, resulting in higher machine performance and productivity.
Key benefits
High transmission capacity
Shrink discs provide a backlash-free and force-locked connection that can reliably transmit high torques and axial forces. This is particularly important in the raw materials extraction industry, where machines operate under extreme loads.
Easy of maintenance
The easy assembly and disassembly of shrink discs significantly reduce downtime and maintenance costs. This ensures higher machine availability and increased operational efficiency.
Durability and reliability
Thanks to their robust construction from high-strength steel or special alloys, shrink discs offer a long service life and high reliability, even under difficult conditions.
Frequently asked questions
How do I choose the right flange coupling?
Selecting the appropriate flange coupling depends on several factors:
Torque: The coupling must be able to transmit the required torque.
Shaft dimensions: The coupling must match the shaft diameters.
Misalignment: For applications where small angular or parallel misalignments occur, a flexible flange coupling should be selected.
Environmental conditions: Environmental influences such as temperature, humidity and corrosion should be taken into account when designing
What errors can occur when assembling a locking assemby?
Uneven tightening of the screws: This can lead to uneven distribution of tension and premature wear.
Dirty surfaces: Dirt or grease on the shaft and hub can negatively affect friction and thus the power transmission.
Incorrect tightening torque: If the tightening torque of the screws is too high or too low, this can impair functionality.
What are the differences between rigid and flexible flange couplings?
Rigid flange couplings: These provide a very firm connection, but require the shafts to be precisely aligned. They transfer the torque directly without elasticity.
Flexible flange couplings: These can compensate for minor alignment errors, vibrations and axial movements, but offer slightly less rigidity.
