These pinion gears attach to a 6mm D-shaft or gear motor using a setscrew. These gears have 20 teeth with a gear pitch of 32P, an outer diameter of 0.688 inch, and a bore of 6mm.
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.
