Servos can be used without gearboxes; however, some applications can benefit from the high torque output by utilizing a gearbox. The output torque is increased by direct proportion to the gear ratio. Inertia balancing is another key reason for using a gearbox. Some applications may have size restraints where a 90-degree gearbox will solve a mounting space issue.

  Planetary gearboxes use high precision helical gearbox motor frame adapter that offer very low backlash and are built for accuracy and reliability. Using a precision gearbox allows for slower output speeds without strain on the servo motor. Here at Automation Direct, we currently carry 2 styles of precision gearboxes. We offer Precision gearboxes for servomotors in Inline, right angle and inline with hub style output. We also offer precision gearboxes that fit small gearbox motor frame adapter such as servomotors, stepper motors or small DC motors.
