CENTAFLEX-DS is the market leader for dual stage couplings. Recommended by leading manufacturers of diesel engines and marine transmissions, the CENTAFLEX-DS is a top-rated patented design. The CENTAFLEX-DS combines the excellent damping characteristics of a torsionally soft flexible roller coupling under partial-load, with the robustness of a stiffer claw-type coupling under full-load. Under low speeds, the roller acts alone. The CENTAFLEX-DS series couplings are mounted with minimal effort, available for standard and non-standard flywheel connections
