We have a wide selection of laser-cut sprockets
for use with the mini tank tracks.
Sprockets consist of two or three plates screwed together to achieve the
necessary 3/8" width and mounting hole. Multiple mounting methods,
sizes, and materials are available, and we can custom-cut sprockets
specifically for your application if one of the standard sprockets does
not fit. We can also customize the sprockets with non-standard colors or
spoke designs.
Please note that because we do not stock every
permutation of material, size, and mounting method, some sprockets are
cut as they are ordered. Therefore, orders that include
sprockets may require one additional business day before shipping.
The following list summarizes the various
available options:
- Material selection
- Clear acrylic is the least expensive option, and it can be
painted for various looks. Acrylic can be more difficult to work
with than ABS when using typical hand tools, and it is more
brittle: an acrylic part can crack if dropped on a concrete
surface.
- Black acrylic is the most aesthetically pleasing option,
though with the same drawbacks as clear acrylic.
- Black ABS is the most durable and the most workable with hand
tools. Therefore, if you plan to modify your sprockets, ABS
could be the best option. However, the ABS sprockets do not look
as nice as those made of acrylic.
- Mounting options:
- 4mm hole. This is the most basic sprocket, with a hole that
fits loosely over a 4mm shaft such as those used in the Tamiya
gearboxes (72001 series). If you need a sprocket to mount on
your own unique actuator, these plain sprockets are a good
starting point.
- We will be adding other mounting configurations soon,
including hexagonal shafts and Solarbotics gearmotor shafts.
Please contact us if you have a particular output shaft that you
would like to use with our sprockets.
- Teeth/diameters:
- Our standard sizes are 6-25 teeth. The diameter of the
sprockets is approximately 0.185" times the number of
teeth. We can custom-cut larger sprockets if you require them.
