These double servo hub arms, crafted from high - quality aluminum, can be directly bolted to the aluminum hub on servo power gearboxes using four 6 - 32 x 3/8' machine screws. Measuring 6 inches in length, they feature a 0.77 - inch hub pattern. Actobotics is an amazing robotics building system. It consists of extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, almost all Actobotics components can be easily and intuitively connected. This wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Dimensions: Length - 6 inches; Hub Pattern - 0.77 inches.

Using this double servo hub arm is quite straightforward. First, locate the aluminum hub on your servo power gearbox. Then, take the four 6 - 32 x 3/8' machine screws and use them to bolt the hub arm to the hub. When handling the product, be careful not to drop it as it might get damaged. To maintain the hub arm, keep it clean and dry. If it gets dirty, you can use a soft cloth to wipe it gently. Avoid using harsh chemicals as they may corrode the aluminum. Store the hub arm in a cool and dry place when not in use to ensure its long - term performance.
