  • Up to 2.500 N for central fixation
Rosta single-rocker AS

Rosta AS single rocker guided one mass shaker systems. The AS single rocker has a decided centre distance.

Two types AS single ronckers in several sizes available

  • Single rocker AS-P for flange mounting up to 2,500 N per unit
  • Single rocker AS-C for central mounting up to 2,500 N per unit

Characteristics for one mass shaker conveyer systems without spring accumulators:

  • Acceleration 1.1 to 1.7 G-forces
  • Conveying speed 6 to 15 m/min
  • Trough lengths maximum 12 to 15 meters 

Characteristics for one mass shaker conveyor systems with spring accumulators

  • Acceleration 1.1 to 2.2 G-forces
  • Conveying speed 6 to 22 m/min
  • Trough lengths maximum 20 meters

Advantages Rosta AS single rocker arm

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

Rosta single rocker arm is multifunctional and 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 single-rocker AS
  • 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.
