These sprockets are custom designed by SuperDroid Robots to fit the 12mm D shaft on our IG52 motors. They are made from high quality steel and have a black-oxide coating. No need to drill into the motor shaft and use rollpins with these sprockets. They have two set screw holes opposite the flat section of the D hole. Each sprocket comes with two 1/4-20 set screws. We use these with our IG52 DB ATR.
Note: These are supposed to be a snug fit on the motor shaft. They may require a little bit of filing to get them to fit.
With it's wide hub and finished bore, this steel roller chain sprocket is ready to mount to a shaft.
100 pack of black UV resistant nylon with flexible tape section, pull tight and does not come undone. Length 6 inches.
This is a prebuilt MLT-JR tracked robot platform equipped with 12V 32-millimeter motors, a motor controller and an authentic Arduino for autonomous control.
