Superior Solution for Shaft Connections in Large Bore Applications

Large cast iron couplings have a bulky design that requires extra room in order to accommodate the oversized outside diameter of the unit. The sheer size of these antiquated couplings puts unnecessary stress on the shaft, and poses risk to damaging the shaft and associated components. In order to attain necessary torque for these applications, cast iron couplings encompass the use of a keyway leading to issues such as wallowing, backlash, fretting corrosion, and fatigue failure, commonly associated with keyways.

Climax provides two solutions for large bore applications. The first solution, H2CC-Series Two-Piece Clamping Couplings, are available with an internal diameter up to 4-15/16”. This all steel rigid two-piece clamping design not only is a lighter weight product with a tighter envelope for clearance issues, but also provides a higher torque capacity over die cast couplings. The clamping design of this steel coupling transmits torque by using keyways. H2CCs are about half the weight of their die cast counterparts and can be installed without major disassembly.
