Good but Tight
Works well but the keyway was slightly tight. Needed minor filing to fit standard key.
Description
This flexible shaft coupling connects motors, servos, and encoders to transmit high torque while accommodating misalignment. Constructed from aluminum alloy, it features a diaphragm design available in single or double configurations with a keyway for secure mounting. The component ensures precise rotational transfer in automation and machinery applications. Verify the specific bore sizes and coupling type match your equipment requirements before installation.
