The 1308 series hub is designed for integrating various rotating components—such as wheels, gears, or pulleys—on 3/16" (4.76 mm) shafts. Despite its light weight (only 5.6 g), the hub provides a rigid and coaxial connection. Four M4 threaded holes are located around the center hole, arranged in a standard goBILDA 16 mm pattern, ensuring full compatibility with construction kit components.
The product is made of high-quality aluminum with a clear anodized finish, protecting the metal from corrosion and giving it a professional appearance. The set screw securely fixes the hub on the shaft, preventing axial displacement and rotation under moderate loads.

This hub is an excellent choice for lightweight robotic platforms and mechanisms where it is necessary to minimize the inertia of rotating parts. The compact flange allows you to install parts almost close to supports or bearings.
When mounting on a shaft, it is recommended to align the mounting A screw with a flat shaft (flattened part) to ensure maximum torque resistance. Using a medium-strength thread locker will prevent the screw from loosening due to vibration during operation.
