Rubber suspension element, DR-A 11×20 (Art. 01 011 013), ROSTA

Possible Applications

This torsion-elastic spring assembly is deployed primarily in vibrating machinery such as linear screens, feeders, and resonance conveyors handling bulk materials in the mining, aggregate processing, and recycling industries. It functions as a resilient pivot mounting for swinging arms and oscillating troughs, effectively absorbing dynamic forces while isolating high-frequency vibrations from the surrounding structural framework. Furthermore, the element serves as a tensioning device in heavy-duty belt conveyor systems and chain drives, where its continuous elastic preload compensates for elongation and dampens operational load peaks. Machine builders also integrate this component into agricultural sorting equipment and industrial compactors to maintain a consistent mechanical linkage under high-cycle reversing loads without requiring lubrication or periodic mechanical adjustments.
