CENTAFLEX-TIR Series torsional couplings are engineered for modern construction equipment, delivering soft progressive characteristics and high allowable power loss to meet the demands of next-generation Stage V engines. Their design enables reduced idling speeds and higher thermal load capacity under alternating loads, resulting in lower fuel consumption, reduced CO2 emissions, and less gear chatter. By allowing system downsizing, such as smaller splitter gearboxes, the CENTAFLEX-TIR improves efficiency while maintaining robust performance.
