ABI 50 Rosta

Free oscillation system Type ABI 50

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 mount 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 mounts prevents the wobbling of the screen casing which is typical of helical spring mounts passing through the resonant frequency.

All ABI oscillating mounts are in stainless steel (AISI 304) and interchang1eable with the blue AB oscilllating mounts.
