Rosta AB
Oscillating mounting maintenance free

  • Maintenance free oscillating mounting
  • Load up to 10,000 N per unit
  • Natural frequencies approx. 2 – 3 Hz
Rosta oscillating mounting AB

Rosta AB oscillating mounting for free oscillating systems. The Rosta oscillating units isolates the vibration and has a low residual force transmission. Rosta oscillating mountings has proven long life time. Examples of more that 20 years at 24 hours operation a day are available.

Advantages free oscillating mountings

  • Easy to install
  • Maintenance free
  • Low wear in operation
  • Screening and separating operations at the same time

Rosta AB oscillating mountings are multifunctional. The AB elements can fulfil 4 functions simultaneously

  • Support static load
  • Forming an oscillating system in which the dynamic spring stiffness is determining the resonance drive-capacity
  • Dictating the direction of oscillation
  • Isolation of vibration and structure-borne noise

Rosta AB oscillating mounting are excellent for several free oscillating systems

  • One mass system circular motion screen
  • One mass system linear motion screen
  • Two mass system with counter frame

The maximum load per standard AB oscillating mounting is 10,000 N, but there are other mountings up to 20,000 N per unit.

Examples of applications are conveyers, sifting machines, etc.
