Semiflex®
The compact precision coupling with high performance
The Semiflex is a torsionally stiff, precision coupling that is without radial restoring forces. Apart from compensating for axial and angular misalignment, the coupling offers high radial misalignment capacity in conjunction with a compact design. The torsionally stiff coupling compensates for misalignment without restoring forces by means of a unique system of two pairs of parallel links arranged at 90° to each other. The angular synchronisation of the connected shafts always remains constant regardless of the misalignment. Examples of use for the precision all-metal couplings are in printing machines, packaging machines and in material-handling equipment.
The Semiflex® series
There are three models
Standard F series - A symbiosis of performance, compact design and generous misalignment capacity. Torque (TKN) 44 Nm to 7,040 Nm. Bore diameter up to 120 mm.
Compact Plus C series - Ideal for limited space. Torque (TKN) 69 Nm to 7,040 Nm. Bore diameter up to 100 mm.
Dynamic D series - The light-weight Aluminum series. Torque (TKN) 40 Nm to 180 Nm. Bore diameter up to 35 mm.
Applications
Semiflex is a torsionally-stiff, precise shaft coupling for transmitting torque from one shaft to another, in those cases where shaft alignment can not be guaranteed due to manufacturing tolerances, assembly procedures, wear, or operational specifics. All types of shaft misalignment are accommodated via the proven Semiflex design. The angular velocity of the connected shafts remains totally synchronised, regardless of the shaft misalignment. No restoring forces are induced. Typical applications are:
- printing machines
- packaging machines
- test units
- material handling
- machine tools
No restoring forces
The unique function system of the coupling compensates for misalignment without deformation and thus without restoring forces.
Compact design
The coupling is characterised by a compact overall axial length that allows the user to realise a space-saving design.
High misalignment capacity
In series production, Semiflex offers a radial misalignment capacity of up to 6.6 mm. Misalignment values up to 20 mm are realised for specific application requirements.
All-metal coupling
The compact coupling has a high torsional stiffness and has a performance-orientated design for high torque transmission.
Combination of different hub versions
The module design system allows the free combination of 6 different shaft mountings.
Individual solutions
We welcome the opportunity to adapt the standard design and optimise it for specific applications. Example:
- For torque requirements up to 250,000 Nm
- For special ambient conditions, for example in a vacuum
- Special dimensions
