These ½” bore hub spacers allow you to space your sprocket, gear, wheel, or other attachment from the mating hub. These hubs utilize the 0.77″ hole pattern common throughout Actobotics. This spacer is ¼” thick.
Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
