Universal aluminium mounting hubs provide a straightforward way to attach wheels, gears or other mechanisms to motor shafts of various diameters. Each hub is machined to fit a specific shaft size and offers threaded holes that accept common set‑screw sizes, giving a secure, repeatable connection. The aluminium construction gives good strength while keeping weight low, and the included Allen wrench and set screws make installation quick and reliable. With options for 3 mm, 4 mm, 5 mm, 6 mm, 8 mm and 1/4 inch shafts, and both metric and imperial screw threads, these hubs adapt to many motor families and simplify integration into robotics, automation and hobby projects.
