These are 4" in diameter omni-wheels with a shaft, collars and a bearing. The traction wheels are made of durable urethane to help grip the floor. The wheels are either single row wheels or double row wheels. The double row wheels provide a little smoother operation, but both work great.
This item also includes a custom machine shaft. The shaft also comes with a bearing that mounts into the gear motor housings, so the load of the robot is not entirely on the motor bearings. Also included is shaft collar for locking the wheel in place and onto the motor. The shaft is made of 6061 Aluminum, so it won't rust.
The shaft is bored with a 6mm hole for mounting onto the IG32 gear motors. If you order our large IG42 gear motor that has a 8mm shaft you will need to enlarge the hole to 8mm. A 4mm hole is also available if you have your own motor you want to hookup to. These shafts are made to order and may require a 3-10 business days before shipment.
This is our LT2-F NIST qualified security robot with an enclosed robot chassis with rear flippers/stabilizers, camera tilt system, custom controller, video console, and battery charging station.
