36mm gearbox

There are a few different companies that stock variants of the same 36mm gearbox. I have two versions of this gear box, one purchased from Long Robotics and the other from Andymark.

Comparison of gearboxes from different

19.1:1 36mm planetary gearboxes. Left has a 8mm hex shaft and is from Long Robotics, right has a 6mm D shaft and is from Andymark.com.

The two gearboxes from different sources are nearly identical once you open them up. All the parts are interchangeable.

Stage 1 reduction in the Andymark gearbox has a nylon gear instead of the sintered metal gear from the long box.
