The new CD® Couplings from Zero-Max combine high torsional stiffness and high dynamic load capacity providing engineers with the right combination to make their designs run faster while maintaining accuracy.

In comparison, bellows-style couplings have high torsional stiffness specifications, but are too brittle to withstand  high speed operation. Beam-style couplings have low torsional stiffness specifications which limit machine speed and accuracy.

According to the company's press release, CD Couplings offer more precision positioning under high reverse loads and reliable 24/7 operation. In addition, CD couplings provide improved chemical and moisture resistance in hostile operating environments that prove difficult or impossible for elastomeric or steel disc couplings.

CD couplings are available in many sizes for numerous servo motor packaging applications.
