The GTM model of servo gear boxes by Bosch are built with a highly precise gearing for maximum positioning accuracy. It is also designed with an enhanced gear tooth forming for reduced noise and power overuse during continuous operation. Its compact, highly robust build make for an optimal, high acceleration torque capacity.

The GTM model is noted for its low backlash and high power density, and can be directly mounted onto servo motors. The models can be used in conjunction with IndraDyn motors in order to achieve optimal acceleration, speeds and position accuracy. Upon request, the model may be supplied with keyway, plain shaft or reduced backlash.
