Destaco�s RR-56 Series of heavy duty, flange output rotary actuators feature a low profile design and bearing supported turn table.


This heavy-duty rotary actuator is ideal for payloads up to 200 lbs [91Kg] in weight. They are available in standard 45, 90, 135 or 180 degrees of rotation. Optional shocks/stops, mid-stop and rotary manifold available.
  • Low profile and bearing supported turn table provides an extremely compact package for tight space applications
  • Payload can be connected directly to the turn table. Eliminates the need for a bearing block
  • Zero backlash, preloaded ball bearings, and slip fit dowel pins make this a very precise and repeatable rotary actuator
