Rosta DO-A 50x200 Rubber Spring Element

The ROSTA rubber suspension unit type DO-A for resonance shaker conveyors is used as an elastic oscillating drive head and/or as spring accumulator in natural frequency shakers. Its high dynamic stiffness, best reliability and maintenance-free functioning are the most important features of this component. The same element DO-A is used especially in general mechanical engineering.

Types with sizes up to 45 have got aluminium housings. Types 50 have got SC iron housings; the inner square sections are made of light alloy with 4 holes allowing to fix them to the eccentric rod or shaker conveyor by means of a fork bracket.
