2. Coupling type coupling model code by the group, breed code, type code, specification code components. Coupling group code, species code, type code, whichever is the code name of the first phonetic alphabet, in case of repetition, then take the second letter Plum elastomer coupling, or the name of the second, third letters of the first and second phonetic alphabet, or the election of its name has the characteristics of word first, second phonetic alphabet, in order to not be repeated in the same category, variety, type in the principle of one another. The main parameters of the coupling nominal torque Tn, the unit is N · m. Nominal torque series sequence number bellows coupling for coupling specification code. 4. Install bolt: penetrating from the outside of the flange bolt holes from the outside of another big hole piercing the flange put buffer sets, spring washers, twisted plum coupling nut with a wrench to tight. Such as the installation or removal of discomfort replace couplings, does not damage the shaft and half-linking, after installation, is rotatably no other fresh as well. 5. Operator Information: Plum coupling should be preceded by checking the boot device Plum coupling nut is loose or off, if you want to in a timely manner with a wrench to tighten the nut.
