A gearbox is a mechanical device that uses a system of gears of different sizes and tooth counts to decrease the output speed of a motor while increasing the torque.
Servo Gearbox Types
GAM has one of the broadest offerings of precision servo gearboxes on the market, with the engineering expertise and manufacturing flexibility to provide custom solutions, providing the best solution for your motion control applications.
Servo Gearboxes differ by the type of gearing used. The gearing affects the precision (measured by backlash), available ratios, and configuration of input to output shaft.
GAM Inline Servo Gearboxes
The input shaft and output shaft are inline. This is achieved by using planetary gearing. The gearing can be straight spur planetary (EPL, PE) or helical planetary (SPH). Helical planetary gearboxes offer quieter operation and higher precision. Inline planetary gearboxes are available in ratios up to 1000:1.
Right Angle Servo Gearboxes
In these gearboxes, the input and output shafts are perpendicular. GAM uses 2 types:
GAM has reduced lead times for most of our custom servo gearboxes.

Other GAM gearbox technologies include:
Because of the different types of gearing and configurations, there is a servo gearbox to fit motion applications. Common features include:
- Shaft, flange, or hollow outputs.
- Included motor adapter customized for your preferred servo motor.
- Backlash less than 8 arcmin, and as little as 1 arcmin.
A servo gearbox is a high precision gearbox typically used between the servo motor and the driven mechanism in a motion control application. It serves two purposes:
- Allows the motor to run in the optimal speed and torque range while producing the desired speed at the driven mechanism.
- Reduces the inertia mismatch between the driven mechanism and the servo motor by the square of the ratio. For example, if the mismatch of the inertia is 100:1, a gearbox with a 10:1 ratio reduces this to 1:1 (mismatch divided by ratio squared)
A gearbox is a mechanical device that uses a system of gears of different sizes and tooth counts to decrease the output speed of a motor while increasing the torque. The arrangement of the gears generally results in the speed at the output of the gearbox being less than the input of the gearbox (motor speed), though there are gearboxes designed specifically to increase speed. Using a speed reducer gearbox allows a smaller motor to be used while still providing the desired torque for the driven system.
Servo gearboxes are used in many precision automation applications. These can include applications such as:
- driving belt actuators
- ball screws
- rack & pinion
- rotary tables
