Channel Mount Gearbox Kit - Continuous Rotation (2:1 Ratio)

A continuous rotation gearbox kit with a 2:1 gear ratio, designed to mount a standard-size servo into Actobotics channel and tubing systems. Threaded side mounts make it easy to incorporate servo-powered rotation into custom pan-and-tilt mechanisms, robotic structures, and mechanical devices.

The kit features a hardened 1/2" stainless steel output shaft with dual ABEC-5 precision ball bearings, rated to support up to 200 pounds of vertical and horizontal load. The output shaft includes a 0.382" bore, allowing you to route wires through the centre axis of the gearbox.
