• MMD: The standard type is equipped with two identical coupling hubs. The transmission elements are fixed in recesses.
• During torque transmission, two elements are always subjected simultaneously to compression by one coupling claw.
• The MMD coupling series includes an extremely compact design and also offers a high transmission rate. It is made of spheroidal cast iron as a standard.
• The coupling halves can be made either in carbon or alloy steel to allow higher interference or lower keyway stresses.
• MMG: The MMG series comprises large couplings for torques up to 630.000 Nm.
• The separate retaining cap allows radial fitting of the flexible elements. This eliminates the need for axial movement of a coupled machine part.
• Again, the screwed connection of the retaining cap is not involved in torque transmission.

Benefits: MMD and MMG couplings,

• Withstands high overloads.
• Are well suited as plug-in type couplings.
• Allow prompt and easy radial change of the flexible elements.
• Ensure ease of assembly and alignment.
• Are maintenance-free.
• Are available in many different types and are adaptable as special designs to almost every type of requirement.
