Unique-Bargains 6mm to 6mm Rotatable Universal Joint Coupler 23x11mm 2pcs

Universal Joint Coupler 6mm Bore

This stainless-steel universal joint couples two 6 mm shafts with a rotatable design that transmits torque while accommodating angular misalignment. The pack contains two couplers, each measuring 23 mm long by 11 mm in diameter and weighing 19 g. Set screws secure the connection for a firm hold.

Build Integration With M4 Set Screws

The M4 set screws lock onto standard 6 mm shafts, so no specialised tooling is required beyond a hex key. Its compact 23 x 11 mm footprint fits tight steering linkages or small-diameter drive lines, freeing space that a bulkier coupling would occupy. Stainless steel resists corrosion in damp or salty environments.

Capacity Limits For Light Torque Loads

The 6 mm bore and 19 g mass suit light-duty torque transmission such as model engineering, instrumentation or small steering shafts. It does not serve high-torque drivelines, larger shaft diameters or applications needing a keyway or clamping hub. Buyers needing greater bore sizes or higher torque ratings should look elsewhere.
