APSOvib® Rubber springs, rubber hollow springs and bushings
Standard antivibration assortment suitable for a wide range of diverse applications to dampen vibrations
Made of elastomers or polyurethane, cylindrical springs are mainly used in the manufacture of punching tools as an alternative to metal coil springs, ensuring the return of the punch to its initial position. Developing large force, they must also offer exceptional lifetimes without losing their initial characteristics. The wide variety of sizes available from stock allows us to meet almost all customer demands.
Rubber hollow springs
Where buffers are used for vibration insulation for machines and installations, rubber hollow springs find their application where long spring deflections are needed. A great variety of elastomers in different Shore hardnesses in combination with metal components offers lots of construction possibilities for versatile applications. They are particularly ideal for applications with very low disturbing frequencies.
Rubber metal bushings
Rubber metal bushings are suitable as torsion springs or supports, requiring no maintenance, for wheel and suspension. They are available in two different finishes, vulcanized or pressed. Key applications are in the fields of agriculture machines and special vehicles, for suspension, axles, torsion bars and shocks absorbers.
The elastomer is vulcanized on the external and internal sleeves. The bush, in a radial direction, is softer compared to the execution with an element in pressed rubber. Vulcanization prevents movements between the outer and the inner sleeves, due to creeping of the rubber. Such a bush has the advantage that it can also be used alone as a torsion spring.
A prefabricated rubber ring is strongly pressed between two concentric steel sleeves and elastically absorbs both the force and the acting torque by friction. The bush therefore becomes subjected to considerable compression on the main load surface, in a radial direction, and reacts extremely rigidly in this direction.
