Hollow Shaft Rotary Actuators

April 1, 2005
The DG Series hollow (through hole) shaft rotary actuators are available in three sizes—60mm (2.36in), 85mm (3.35in) and 130mm (5.12in).

The output table of the DG Series rotary actuator permits the user to directly couple to the application load. A single stage reduction gear mechanism increases the diameter of the driven gear in the output table that enables a large through-hole configuration. The gear reduction mechanism achieves a repeatability of +/-15 arc-seconds and a total lost motion (backlash) of less than 2 minutes. The 60mm rotary actuator achieves a permissible torque of 7.9 lb-in. The 85mm and 130mm high rigidity models develop a permissible torque of 24 lb-in and 106 lb-in respectively.
