    The difference between one diaphragm coupling and two diaphragm coupling
    Diaphragm couplings are generally divided into one diaphragm couplings and two diaphragm couplings. The difference between the two is the ability to handle various deviations. In view of the complex bending of the diaphragm, the single diaphragm coupling is not well adapted to eccentricity. The double diaphragm coupling can bend in different directions at the same time to compensate for eccentricity.

    Existing reviews of One Diaphragm Coupling, 8mm to 16mm
    Great 8-16mm one diaphragm coupling
    I assemble a 3D printer and a laser cutting machine in my free time, and try to use various types of couplings. This is the best so far, and I sincerely recommend you to buy it.
