When the tolerance is above the allowable value, over-high torque or above the allowable value of shaft tolerance, the coupling will deform plastically and shorten its life.
If there is any abnormal mechanical noise in operation, please stop the operation immediately, then confirm the cause: deviation, screw loose, or the rotating object be hindered before restarte operation.
If use on a heavy load equipment, please use glue to prevent screws getting loose or choose a bigger size coupling.
The rated torque means the continuous torque capability of the coupling.
The maximum torque refers to the instantaneous torque capability of the coupling.
