These ½' bore hub spacers are great for spacing your sprocket, gear, wheel, or other attachments from the mating hub. They use the 0.77' hole pattern common in Actobotics. This spacer is ½' thick. Actobotics is a robotics building system featuring extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, almost all Actobotics components can be easily connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Documents include SketchUp Part and Product Page (545384).

Using this 1/2 inch bore hub spacer is easy. Just place it between your sprocket, gear, wheel, or other attachment and the mating hub. Make sure to align it with the 0.77' hole pattern. When handling, be careful not to damage the spacer. For maintenance, keep it clean and dry. If it gets dirty, you can use a soft cloth to wipe it. Avoid using harsh chemicals as they might damage the surface. Store it in a safe place when not in use to prevent any physical damage.
