These ½ - inch bore hub spacers are a great addition to your Actobotics toolkit. They let you create space between your sprocket, gear, wheel, or other attachments and the mating hub. The spacers use the 0.77 - inch hole pattern that's common across Actobotics. With a thickness of ¼ inch, they're just right for your projects. Actobotics is an amazing robotics building system. It's built around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to two standardized hole patterns, almost all Actobotics components can be easily and intuitively connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects.

Using these hub spacers is easy. First, find the sprocket, gear, wheel, or other attachment you want to space from the mating hub. Then, simply place the ¼ - inch thick spacer between them. Make sure the 0.77 - inch hole pattern on the spacer lines up with the holes on the components. When it comes to maintenance, keep the spacers clean. You can use a dry cloth to wipe off any dust or debris. Avoid using harsh chemicals as they might damage the surface. Also, store the spacers in a dry place to prevent rusting. And always double - check the hole pattern alignment before using them in your projects to ensure a proper fit.
