Innovations 2026

More performance.
Smaller footprint.

Sometimes innovation isn’t about more, but about doing things differently. The GRUEBER oval spring rethinks the classic buffer spring: its oval cross-section makes more efficient use of the available installation space, enabling high power density within a compact footprint.

Compared with individual springs requiring the same installation space, performance increases of up to 30% are possible. At the same time, conventional spring sets can be replaced by a single oval spring – turning two into one. This not only reduces the required installation space and weight, but the resulting weight savings can also contribute to reducing CO₂ emissions.

Next-Generation Springs

The key difference lies in the cross-section: instead of arranging two springs inside one another, the oval spring uses a specially developed oval geometry. This makes more efficient use of the available installation space for the spring action. The result is a more compact design and new possibilities for applications where performance, weight and installation space are equally critical.

Where installation space is limited or existing spring systems reach their limits, the oval spring opens up new design possibilities. It can simplify existing solutions, free up space for other components, or help make systems more compact and lightweight. In this way, a new spring geometry creates genuine design freedom for the entire system.
