These hub-mountable aluminum sprockets can be used to drive wheels or other sprockets with 0.25' chain. They have 24 teeth with a spacing of 0.25', an outer diameter of 2.049', a bore of 1/2', and utilizes the 0.77' hub pattern.

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.
