Rosta single joint AV

The Rosta oscillating mountings type AV are maintenance-free elastic joints designed for guiding circular motions of hanging screens such as gyratory sifters and screens in flour mills, chemical processing plants and paper mills. The rubber inserts of these oscillating mountings are larger than the ones of the other Rosta elements. Therefore they intensively absorb the vibrations of the hanging sifters and better protect the building structures and ceilings.

The Rosta oscillating mounting can fulfill 4 important functions simultaneously

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

Rosta single joint AV
  • Quick response, short lines
  • Renowned manufacturers
  • Profound product knowledge
  • High reliability

We supply slewing ring bearings, oscillating mountings, tensioner devices from stock and we also have spiral bevel gearboxes, servo gears and electromechanical actuators in our delivery program.


In addition we also select and offer the right components and systems for motion control solutions, such as servo gear motors, linear servo actuators and complete XYZ cartesian systems.
