The resilient Max-C® coupling is a non-lubricated flexible coupling. It is designed to transmit torque via rubber or urethane element under compression, with dampening or cushion. The MAX-C® resilient coupling is available in three styles-K2, WB and CB. Fourth style-UB (urethane cylindrical block design) has been
superseded by the K2, but is still available for sale. K2: Urethane wedge shaped blocks. Used on electric motor driving cranes, pumps, feed rolls, fans, conveyors bow thruster, manipulators, etc.

WB: Rubber block in wedge shape. The rubber blocks come in various shore hardness and are typically custom-engineered for an application.
They are used on synchronous and variable frequency motors driving, for example:
- Compressors
- Klin drives
- Steel mill main drives
- Crushers
- ID and FD fans
These come in a wide range of sizes and torque capacity.

CB: Rubber blocks are cylindrical shape also ,available in various hardness, like the WB design. They are available in various sizes and torque ranges, typically custom-engineered.

They are primarily used in the following applications:
- Diesel engines driving generator sets
- Fire pumps
- Torque converters
- Marine drives
- Drill rigs
- Main propulsion
