Rosta AB-HD
Oscillating mounting heavy duty

  • For higher loads than standard AB
  • Load up to 60,000 N per unit
  • Natural frequencies approx. 2,5 – 3,5 Hz
Rosta oscillating mounting AB-HD

Rosta AB-HD oscillating mounting for free oscillating systems. AB-HD is a “Heavy Duty" version of the AB mount. The AB-HD type offers 40 % more load capacity compared to the standard AB version. The Rosta AB-HD oscillating unit 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. 

The maximum load per standard AB-HD oscillating mounting is 60,000 N per unit.

Advantages free oscillating mountings

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

Rosta AB-HD oscillating units are multifunctional for 4 simultaneous functions

  • 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

Application Rosta AB-HD oscillating mounting for several free oscillating systems

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

Examples of applications are

  • Shaker conveyers
  • Sifting machines
  • Screens
  • Etc.
