Advantages of the ROSTA elements

The rubber spring element can fulfill several functions in a compact space: as a torsion spring, pivot bearing and anti-vibration mount in one unit!
The element works without any noise and is maintenance-free.

Technical description

The ROSTA element is a jointed spring with four pre-tensioned special rubber bodies between housings and a inner square profile offset by 45 degrees. Due to the high friction, no axial retention is necessary.
The element has no metallic contact or friction locations.
The working angle is a maximum of +/- 30 Grad.
The inertia of the natural rubber provides energy damping during turning movements as a result of the flexing friction of the rubber bodies.

Customer benefits

Thanks to the multi-functionality of the ROSTA element, savings can be made in the initial investments through the avoidance of expensive bearing and damping components.
The maintenance-free operation lowers operating costs through the longer service intervals. The guaranteed functionality increases the availability of installations and machinery.
