Bi-directional travel stops

ACTREG rack and pinion actuators are provided with bi-directional pinion travel stops

Side located stops allow a full ± 5º travel adjustment between 85º and 95º. These travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact loads associated with recommended travel speed

Adjustment of the anticlockwise and clockwise rotation limits is accomplished by unscrewing the locking nuts, turning the respective left and right stop studs to reduce or increase the travel angle and screwing the locking nuts

Testing for all actuators

All actuators manufactured by our company are individually tested in a state-of-the-art electronic testing facilities.

Testing is carried out to check the leakage in both internal and external, the angle of rotation and torque values.

All bodies are stamped with year, month of production, size and serial number.
