These ½ - inch bore hub spacers are a great solution for spacing your sprocket, gear, wheel, or other attachments from the mating hub. They use the 0.77 - inch hole pattern that's common in Actobotics. With a thickness of ¾ inch, they're a reliable choice. Actobotics is a robotics building system featuring extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to two standardized hole patterns, you can easily connect nearly all Actobotics components. This wide range of components makes it possible to build complex electromechanical prototypes or finished projects.

Using this hub spacer is easy. First, identify the sprocket, gear, wheel, or other attachment you want to space from the mating hub. Then, simply place the ½ - inch bore hub spacer in the right position. When installing, make sure the 0.77 - inch hole pattern aligns correctly with the corresponding parts. As for maintenance, keep it clean from dust and debris. You can use a dry cloth to wipe it down regularly. If it gets dirty, you can use a mild cleaner and then dry it thoroughly. Be careful not to use abrasive materials that could scratch the spacer. Also, store it in a dry place to prevent rusting.
