This Martin Quadra-Flex coupling sleeve is for use on specific Martin flange types (J type flanges in the case of JEM and JEMS type sleeves, and all flange types in the case of EM type sleeves) in the Quadra-Flex series flexible coupling assemblies. It is made of thermoplastic rubber for resistance to oil and an operating temperature range of -50 to 275 degrees F (-46 to 135 degrees C).Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts.
