ROSTA oscillating mountings type ABI are maintenance-free elastic rockers for the support or suspension of freely oscillating vibrating equipment with a wide variety of designs and drive systems. They assist the driving forces in the conveying direction and assure good linear guidance of the oscillating part of the machine. The pantograph structure of the oscillating mounting allows large spring deflection under load, which results in low natural frequencies (down to approx. 2.2 Hz) and hence exceptionally high insulation efficiency towards the support structure. The great lateral stability of ROSTA oscillating mountings prevents the wobbling of the screen casing typical of helical spring mountings on passing through the resonant frequency.
