Rosta AK
Elastic joints

  • Universal joint for support or suspension
  • For oscillating gyratory sifting machines
  • Load up to 40,000 N per unit
Rosta universal joint AK

The Rosta universal joints type AK are maintenance-free elastic joints which can be moved in any direction. They are used as universal joint supports for mounting or suspending gyratory screens, screening tables, tumbling oscillators, sorters and screening machines positively driven by eccentrics or freely oscillating with unbalanced drive.

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 universal joint AK
  • 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.
