Our largest rubber caterpillar track. With a diameter of 139mm (length 455mm) and a width of 34mm makes this track suitablr for the larger model.
Running down the inside centre are teeth on a 10mm pitch. The track can be driven by friction drive or by having a drive wheel with matching tooth holes on also on a 10mm pitch. Referring to the additional images, we show the belt with two solid aluminium T10 timing pulleys for 16mm wide belts. These are a perfect match and great for high torque drives with high power motors. You will still need to devise a method to keep the track centred on the pulleys i.e. a couple of bands around the pulley to form a centre groove.
An alternative for a friction drive is with 4 off our polythene wheels 4603-030 per wheel. See the photo above for this but should work a treat for lighter duty applications.
