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superseded by the K2, but is still available for sale.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

Features:

• Provides resilience and damping for severe applications.
• Can increase drive train and gear component life.
• Does not need routine maintenance.
• Available up to 79.5" (2.2M) OD.
• Peak torque capacity of 56 million in-lb. (6383 kN-m).
• Maximum bore up 34" (864mm).
• Off-the-shelf and custom designed for application.
• Resilient blocks available in rubber or urethane - depending on the application.
