ROSTA SCHUDELEMENT AB 50-2

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 and hence exceptionally high insulation efficiency towards the support structure. The great lateral stability of oscillating mountings prevents the wobbling of the screen casing typical of helical spring mountings on passing through the resonant frequency.
