Flexible Coupling Hub - 1/4" Bore

Surplus replacement hub for flexible CNC couplings. This hub fits a 1/4" motor shaft or 1/4" lead screw and can be used for repairs, spare parts, replacements, or custom CNC machine builds.

Important: This is one hub only. It is not a complete coupling. To create a complete flexible coupling assembly, you will need two hubs and one spider insert.

Best used for:

• Replacing a worn or damaged coupling hub
• Keeping spare CNC coupling parts on hand
• Custom CNC router, mill, laser, or automation builds
• Matching 1/4" shafts or 1/4" lead screws
