This is a complete set of wheels (2 drive wheels and 2 idlers) with two matched tracks. You need 1 of these for the LT2 or LT2-F. These track and wheels will not fit on a original LT or LT-F chassis. These generation 3 tracks are a more aggressive pattern than the standard LT2 tracks.
The LT2 tracks are designed specifically for the LT2 Tactical Surveillance Robot. These tracks are designed and built to take extreme abuse. They are the same tracks that passed the rigorous NIST qualification testing. The guide cleats are tapered and made of black UHMW. The wheels are also chamfered to match the guide cleats. These LT2 tracks do a excellent job of staying on track in the harshest of situations.
The wheels are CNC cut from 1/2" thick rubber and sandwiched between 1/2" UHMW. The UHMW is then chamfered to match the track internal cleats. The idler wheels are the same as the drive wheels, only no teeth on the 1/2" thick rubber and no drive sprocket. Each wheel has 1/2" ID bronze bearings through them. The drive wheels have a #25 32 tooth chain sprocket mounted to them. The wheels come assembled.
The tracks are ~2 7/8" wide and have CNC machined timing holes on them to match the LT2 drive wheels. The tracks have UHMW guides attached to the sides for better tracking using a custom CNC made jig. The track is spliced together with a alligator clip. The nominal center to center distance of the wheels are 19 7/8". If you are not using this with the LT2 your design must allow for alignment and tensioning. These tracks are a more aggressive pattern than the standard LT2 tracks. They are thicker and have a more aggressive pattern for climbing, but they will result in higher current draw and more vibration than the standard LT2 Tracks.
The complete track and wheel set weighs ~ 10.5 pounds and is built to order. Please allow 1-3 weeks for shipment.
