The Centaflex-KE series from Centa was developed to minimize negative forces and improve diesel-driven hydrostatic construction machinery with nonstandard engine flywheels and flange-mounted pumps such as excavators, vibratory rollers, and loaders. Such equipment is typically connected by torsionally stiff couplings that shift and can cause minor radial misalignment. The Centaflex-KE series features a torque range up to 650 N·m (480 lb·ft) and offers high torsional stiffness with sufficient radial flexibility. The coupling disc consists of glass-fiber-reinforced plastic with cylindrical chambers on the outer diameter. Pressed-on, heat-resistant elastomer rubber bushes in the chamber are arranged to allow play between the rubber bush and coupling disc, resulting in radial adjustment. Other features include metal-like strength, improved sliding qualities, and lack of corrosion at the splined pumpshafts. Couplings are pre-assembled as a unit and are bolted to the flywheel.
