(1)CouplingThe chooser should choose the appropriate coupling balance level;
(2) Whether the unbalance of the coupling can meet the needs of any kind of rotating system depends on the performance of each special connected machine, and it is best to be determined by the manufacturer of the connected machine.It is recommended that each machinery manufacturer drafts an appropriate flexible coupling balance level while providing its design;
(3) If the appropriate coupling balance level cannot be obtained from the machine manufacturer, it can be used as a reference guide for general users;
