These Actobotics clamping hubs are an excellent and budget - friendly option for attaching hub - mount gears or wheels to shafts or tubes. Unlike set - screw hubs, they won't damage the items you're clamping. This clamping hub features a 3/16' bore, four 6 - 32 tapped holes, one 6 - 32 machine screw for tightening, and uses a 0.77' hub pattern. Actobotics is a robotics building system that uses extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, almost all Actobotics components can be easily connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Dimensions: Bore - 3/16', Hub Pattern - 0.77'.

Using this Actobotics clamping hub is easy. First, place the hub around the shaft or tube where you want to attach the gear or wheel. Then, use the 6 - 32 machine screw to tighten the hub by screwing it into the tapped holes. Make sure it's secure, but don't over - tighten to avoid any potential damage. When handling the hub, be careful not to drop it as it might get dented or misaligned. For maintenance, keep it clean from dust and debris. You can use a dry cloth to wipe it down regularly. If it gets dirty, a mild soap and water solution can be used, but make sure to dry it thoroughly afterward. Store the hub in a dry place to prevent rusting.
