Mechanics: The Top Mount Servo Gearbox framework is fully machined from 6061-T6 aluminium and anodized to resist scratches and wear. The 3/8" diameter solid stainless steel output shaft is supported by a pair of ABEC-5 double shielded ball bearings for smooth operation no matter the orientation of the load. The Top Mount Servo Gearbox has tabs on the top edge of the gearbox so that it can be recessed and mounted to a flat surface with minimal deck-height.  An excellent choice for R/C sailboats, steering assemblies and custom robotics projects.

Electronics: The servo installed into the gearbox gets modified and connected to an external potentiometer so that the amount of rotation is not limited by the servo but dependent on the relationship between the output shaft of the gearbox and the potentiometer connected to it. This patented setup allows the TM-9380TH-180 to rotate up to 180 degrees. An assembled servo gearbox will plug into a servo controller just like any other servo; no additional wiring will be necessary to put it to work!
