Description
This flexible elastic connector serves as a figure-8 encoder coupling designed to join small motors with lead screws. Constructed for flexibility, it accommodates minor misalignments while transmitting rotational motion between shafts. The component features a specific figure-8 geometry suited for compact mechanical assemblies requiring precise movement transfer. Ensure the motor and screw shaft diameters match the coupling's specifications before installation to maintain optimal performance.
