6 tooth sprocket ASM on a hub and 2 inch track system

I’m using a 2 inch track and would like to use the 6 tooth sprocket. What hub do I need to use in this application?

@brandonbdxtreme Welcome to the RobotShop Community. Regarding the following two products:


The following hubs are compatible (for 6mm diameter shaft):

Hub for 4mm diameter shafts:

Idler hub:

Normally you need two sprockets back to back at each motor and idler location (as opposed to just one). happy to help if you have any additional questions.

how does the sprocket assemble onto the idler hub? I have downloaded the files but cant seem to see how they are assemble correctly to work.

A good reference is the Tri-Track assembly guide:

The sprockets are assembled back to back at the right angle (steps 6 and 7).
