About ROSTA
ROSTA AG, headquartered in Hunzenschwil (Switzerland), has been a manufacturer of spring and damping systems based on maintenance-free rubber torsion spring technology for over 80 years. The product range includes vibration elements for free-swinging and guided systems, rubber spring elements, vibration dampers, levelling feet, tensioning elements and motor brackets. In addition to standard products, the company develops custom assemblies as an application specialist, including welded fabrications, painting, cathodic dip coating (cataphoresis) and application-specific calculations. The components are used, among other things, in screening plants, conveying and vibrating troughs, drive tensioning systems and vibration isolation. Covered industries range from mining, agriculture, recycling and wood processing to food & beverage, e-mobility, marine and playground equipment. Materials used include galvanized steel, stainless steel (AISI 304), aluminium and elastomers such as Rubmix 40. Distribution takes place worldwide through its own subsidiaries and sales partners.
