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 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.
