About ROSTA
ROSTA AG, headquartered in Hunzenschwil (Canton Aargau, Switzerland), has been developing and manufacturing spring, bearing and damping systems for industrial vibration applications for over 80 years. The core competence is maintenance-free rubber spring torsion technology, used in rubber spring elements, oscillating elements for free-swinging and guided systems, vibration dampers, levelling feet, tensioning elements and motor bases. The components combine elastomers (including natural rubber and the heat-resistant rubber compound Rubmix 40) with metals such as steel, stainless steel AISI 304, stainless steel casting 1.4308 and aluminium; for Custom Products, ROSTA offers welded constructions, painting and cathodic dip coating (KTL). As an application specialist, the company develops customised solutions together with customers, including application-specific calculations, ATEX-compliant variants and digital sensor service offerings (ROSTA Digital). Fields of application include mining, bulk material handling, food and agricultural technology, recycling, e-mobility, rail and commercial vehicles, wood processing, marine technology as well as outdoor gyms and playgrounds.
