These 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 has a 3/8' bore, four 6 - 32 tapped holes, one 6 - 32 machine screw for tightening, and uses the 0.77' hub pattern. Actobotics is a robotics building system featuring 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 - 3/8'; Hub Pattern - 0.77'.

Using this clamping hub is quite simple. First, align the hub with the shaft or tube where you want to attach the gear or wheel. Then, insert the hub onto the shaft. Use the 6 - 32 machine screw to tighten it through the four 6 - 32 tapped holes. This will securely fasten the hub in place. When using it, make sure not to overtighten the screw, as it might cause damage to the hub or the item being clamped. For maintenance, periodically check the tightness of the screw. If it gets loose, tighten it gently. Keep the hub clean and free from dust and debris to ensure smooth operation.
