SGFlex - Flexible Discs

Proven technology from the automotive sector meets industry. The “hardy disc” or flexible disc familiar from the automobile is used for all power transmission. It has excellent damping properties.

Made in Germany

No one prefers to work under pressure – and that goes for materials, too. It is much better to pull together. This is the basic idea behind our technology, which is based on the SGF tractive force principle.

SGF tractive force principle
With the unique SGF tensile force principle, we create industrial marvels that transmit power almost exclusively via the vulcanized cord inlays as tensile force. This meticulous and precise technology is the secret of our extraordinary resilience and reliability.

Tenpu® fiber technology
But that is not all. Our specially developed fiber packages with Tenpu® fiber technology are true multi-talents: They dampen power peaks and absorb start-up shocks, while the elastomer performs a protective function for the fiber packages. But this inconspicuous component does even more: it isolates noise and interrupts structure-borne sound, ensuring extremely quiet and efficient performance.

Here at SGF, we’re about more than just products – we’re about creating reliable, high-performance connections that help you achieve your goals. So if you’re looking for the diamond of industrial couplings, you’ve come to the right place. 

Years Experience
Thanks to the traction principle, the SGFlex can transmit power in a small installation space.
Customized solution for your application

SGFlex Variants

Tenpu® fiber technology is adaptable so that it can be pressed into different shapes. Either in a link coupling form, a flexible disc or pressed together to form a link coupling. This means that torques of up to 16,000 Nm are no problem. Thanks to this shape, we can install couplings in the smallest possible installation space. The SGFlex is the basis for our flexible discs and flexible drive shafts.

Link Elements

Link elements can be wound and vulcanized in almost any size. Which makes it an incredibly flexible product to use.

Flexible Disc

The classic is the flex disc. In use millions of times. The loops are wound into a ring and vulcanized together.

Link coupling

Link couplings are lugs pressed together to form a ring. The advantage is the flexible production of different power sizes with one lug size.

Everything from one hand

SGF is your development partner for automotive. Together we develop products that meet individual requirements. Thanks to over 75 years of experience we are able to develop solutions for the most demanding tasks.

In-house materials laboratory

When developing products, we use state-of-the-art materials laboratory to ensure best possible solution for your application. In doing so, we develop and process various elastomer compounds (NBR, SBR, EPDM, silicone / VMQ) according to requirements.

Virtual product development

Virtual product development includes multi-body simulation (MBS), finite element method (FEM)  and FKM evaluation (strength verification). Rapid prototyping is used to verify calculation and measurement.

In-house Testing

Validation of design and products done in-house according with customer specifications.
