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. With a 4mm bore, four 6 - 32 tapped holes, one 6 - 32 machine screw for tightening, and utilizing the 0.77' hub pattern, they offer great functionality. Actobotics is a robotics building system featuring extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to two standardized hole patterns, most Actobotics components can be easily connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Dimensions: Bore - 4mm, Hub Pattern - 0.77'.

Using these clamping hubs is easy. First, place the hub on the shaft or tube where you want to attach the hub mount gear or wheel. Then, insert the 6 - 32 machine screw into the tapped holes and tighten it gently. This will secure the hub in place without damaging the shaft or tube. When using these hubs, make sure the 4mm bore fits properly on your shaft. Don't over - tighten the screw as it might damage the hub or the attached component. For maintenance, keep the hubs clean and free from dirt and debris. You can use a soft brush to clean them. If the screw gets loose over time, just tighten it again. And that's all you need to know to make the most of these clamping hubs.
