Abstract: The present invention relates to a pressure mounting slip coupling, wherein it is possible to transmit power in spite of an eccentricity or a declination generated in the axial direction, block a torque overload, flexibly correspond to the change of the distance between shafts, and improve durability and operation stability with an insulation function. The pressure mounting slip coupling (1) has one side flange (11) coupled with a brake disc (2), which is connected to the output shaft (O) of a motor, and another side flange (12) coupled with a flange (3), which is connected to the input shaft (I) of an object to be driven, so that the output shaft (O) of the motor and the input shaft (I) of the object to be driven are connected to each other.
