We bring the future to rail


Whether power transmission for powerful acceleration or effective damping of vibrations  – components from SGF ensure train operation that is as reliable as it is comfortable.

SGF, that's
Railway - Expertise

Late in the evening on the train on the way back from a business meeting. Within a few minutes, your train accelerates to an impressive 300 kilometers per hour. At the end of the day, you and your colleagues treat yourself to a fresh draught Pilsner in the on-board restaurant. You drink it relaxed at the bar table.

Sounds good? It is. But neither the lightning-fast yet gentle acceleration of the train nor drinking beer standing up would be possible without the appropriate technical components. 

This is exactly where we come in. With our products for power transmission, we provide plenty of thrust. With our solutions for vibration damping, we make a significant contribution to ride comfort. So that you can continue to enjoy your rail journey in the future.

Years Experience
We are convinced that cord-reinforced silicone components will be used in every modern rail vehicle in the future due to their superior material and product properties!

Everything from one hand

SGF is your development partner for railway. Together with our customers, we develop products that meet individual requirements. Thanks to over 75 years of experience and our state-of-the-art equipment, we are able to develop solutions for the most demanding tasks. Ready-to-assemble systems made of elastic components with flanges or adapters can be developed, tested and produced due to our great competence.

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.
