    Tips: Diaphragm coupling application

    Diaphragm couplings are widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining Machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and generator sets high-speed, high-power mechanical transmission systems, which are applied to high-speed transmission after dynamic balance shafting.

    Existing reviews of Two Diaphragms Coupling, 10mm to 20mm
    I bought the right size
    I installed some of these 10mm-20mm double diaphragm couplings, the right size, a single screw on each end tightens the collar around the respective shaft, I use it to attach the motor to the lead screw on the small linear slide, they works great.
