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 need to clamp. With a 6mm bore, four 6 - 32 tapped holes, one 6 - 32 machine screw for tightening, and a 0.77' hub pattern, they're a reliable choice. Actobotics is a robotics building system using 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 building complex electromechanical prototypes or final projects possible. Dimensions: Bore - 6mm, Hub Pattern - 0.77'.

Using this 6mm bore clamping hub is easy. First, place the hub on the shaft or tube where you want to attach the gear or wheel. Then, insert the 6 - 32 machine screw into one of the tapped holes and tighten it to secure the hub in place. Make sure not to over - tighten the screw, as it could cause damage to the hub or the item you're clamping. When it comes to maintenance, regularly check the tightness of the screw. If you notice any looseness, gently tighten it. Keep the hub clean from dust and debris, as this can affect its performance. Also, store it in a dry place when not in use to prevent rusting.
