CD Couplings Boast High Power Density & Small Footprint


CD couplings provide precise and reliable shaft connections in less space than similar types. They operate without fatigue 24/7 as required in the latest machine designs. Their composite flex element delivers high torsional stiffness, yet allows for misalignment in high stress applications. Also, the couplings afford smooth operation at high speeds. They perform at peak torques in the most hostile operating environments—from extreme cold to hot weather conditions (–70 to 250°F). Applications include drive trains, gear boxes, and generators.
