These clamping hubs are an excellent and budget - friendly option for attaching hub mount gears or wheels to shafts or tubes. If you're worried about damaging the items you need to clamp, they're a better alternative to set screw hubs. The clamping hubs feature a 3mm bore, four 6 - 32 tapped holes, one 6 - 32 machine screw for tightening, and use the 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 - 3mm; Hub Pattern - 0.77'.

Using this clamping hub is easy. First, select the hub - mount gears or wheels you want to attach and the corresponding shaft or tube. Then, place the clamping hub on the shaft or tube. Use the 6 - 32 machine screw to tighten it through the four 6 - 32 tapped holes. When doing this, be careful not to over - tighten to avoid damaging the parts. As for maintenance, keep the hub clean and free of debris. Periodically check the tightness of the machine screw. If you notice any signs of wear or damage, it's a good idea to replace the hub. And remember, this clamping hub is part of the Actobotics system, so you can connect it with other components as needed to build your robotics projects.
