The 4 inch (100mm) aluminum Mecanum wheel is comprised of a series of rollers, mounted so that their axis of rotation is 45 to the axis of the main wheel. As the wheels rotate in sync, the vehicle moves forward or in reverse normally, but by spinning pairs of wheels in opposite directions, the rollers enable sideways movement. Put it all together and you can move forward, backward, laterally, diagonally, or spin in a circle. Also included are twelve extra bolts (60 mm long) for bolting on the 6mm Nexus aluminum wheel hub or the 8mm Nexus aluminum wheel hub.
Each roller is supported by plastic sleeve bearing. These wheels will not support as much weight as our other 4" Mecanum Wheels with Ball Bearings.
Several wheel hub options are available for you to select from below.
These heavy duty 8 inch (203mm) aluminum mecanum wheels allow your robot to easily move laterally, diagonally, or spin in a circle. This set includes four wheels. These use ball bearings for smooth operation and high load capacity.
This is a direct drive 4WD base robot kit that uses Nexus mecanum wheels and hubs. It's a great robot platform for indoor robotics. It can vector in any direction.
This is our IG42 DB Heavy Duty Vectoring All-Terrain Robot Chassis. It is designed for our IG42 motors with 6 inch mecanum wheels.
Use these roll pins to fix sprockets to a shaft and keep them locked in place.
