CENTAFLEX-DS Series Torsional Couplings

The CENTAFLEX-DS is a dual stage coupling series with smooth operation and a reliable load transmission standard designed to eliminate gear chatter.

Dual Stage Coupling with Progressive Characteristics

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.

More About CENTAFLEX-DS

Why Do Customers Choose the CENTAFLEX-D?

Dual Stage

The CENTAFLEX-DS offers dual stiffness, operating initially as a torsionally soft coupling for low loads and speeds and a stiffer coupling for high loads and growing speeds. This patented dual stiffness characteristic eliminates damaging torque reversals and related gear chatter in transmission systems.

Versatile

The coupling offers design flexibility, available for standard and non-standard flywheel and marine transmission connections with a flanged housing to allow for splined or tapered input shafts.

Runs Quiet

Low torsional stiffness leads to resonance frequencies far below idling speed, damping torsional vibrations, avoiding gear noise and allowing for smooth, quiet operation.

Heat Resistant

The CENTAFLEX-DS features a heat-resistant compressed rubber element and the coupling has internal ventilation for excellent heat dissipation.

CENTAFLEX-DS

The CENTAFLEX-DS is a fail-safe design based on years of engineering research and proven components. Intensive testing, torsional vibration calculations, and field application have verified the CENTAFLEX-DS as an unsurpassed duel-stage coupling solution. With silent operation and a compact, reliable, and economic design, the CENTAFLEX-DS is ideal for use in main propulsion drives between diesel engines and flange-mounted gear, auxiliary drives with high idling, and between diesel engines and independently mounted gear if both are rigidly mounted and well-aligned. For smooth, quiet operation at very low idling speeds, and a robust torque transmission at higher speeds, the CENTAFLEX-DS is an ideal solution.
