Discontinuation notice: We are now selling this product under a different product number in packs of 10. The replacement product is identical to this one, except instead of ordering quantity 10 to get 10 loose track links, you order quantity 1 to get a 10-pack of links.


These miniature tank tracks are great for small, indoor, tracked robots. Each track link is injection-molded from ABS, and the links are held together by 1/16″ stainless steel dowel pins. The track is 0.9″ wide, and the pins are spaced approximately 0.54″ apart. These tank tracks are smooth for operation on one of the most common types of terrain that your robot might encounter: carpet! The tracks are designed to work injection-molded sprocket sets that allow for a variety of actuator options:

The picture above shows a belt of 18 links, with 8-tooth sprockets at both ends, in each available color: black, red, yellow, and blue. This is close to the minimum practical belt size, while 50 links would be getting close to the longest practical track length. Different colored links can also be used together to create custom multicolored tracks.
