AR rotary actuators with plate
   
The AR series of rotary actuators are designed to be compact, rugged and with high torque.
 
° The angle of rotation can be adjusted to provide an extra 2° of stroke by adjusting either of the two threaded pushrods and stop block assemblies built into the cap (optional).

° The Stop function is made directly on the spindle assuring precise, reliable performance.

° Deceleration is guaranteed by hydraulic shock absorbers with integrated pressure-tight cartridges that act of the rack pistons. The rotation control feature is integrated into the actuator housing and rotation is detected by two sensors that detect a magnetic field generated by a magnetic ring fixed to one of the pistons. An optional proximity sensor kit is available to detect spindle position.

° All versions have an internal circuit that feeds both sides of the piston (to obtain maximum torque) which is connected on one side only, to save space. The actuators can be operated with either air or oil, with appropriate operating pressures indicated in the “specification.”

° The actuator body is constructed out of hardened anodized aluminum alloy. The rotation spindle, gears, and pistons are made from UNI 39 NiCrMo3 nitride-hardened steel.

° Spindle rotation, supported on pre-stressed oblique’s and drilling lock nut, is assured by a pair of rack pistons made out of treated steel.
