Coupling suits construction vehicles and
plant
The new Centaflex-KE coupling has been specially developed to meet the demanding requirements of excavators, vibratory rollers, loaders and other plant.
Centa, the world-leader in propulsion and coupling technology, has launched a new and innovative coupling system for construction vehicles and plant The new Centaflex-KE coupling has been specially developed to meet the demanding requirements of excavators, vibratory rollers, loaders and other plant and combines the unique combination of high torsional stiffness and simultaneous radial flexibility to optimise hydrostatic diesel drives in the low or medium power range

Multigear for high torque, low speed demands
Specifically designed for high torque, low speed applications, the Centa Multigear units operate in the 5,000Nm to 550,000 Nm output torque range with output speeds generally less than 5 rpm.
Gear units ideal for low speed repetitive use
Custom designed Centa Zerogears combine zero backlash with high torsional stiffness and low mass moment of inertia.
Until now, diesel powered construction vehicles with flange connected hydraulic pumps have predominantly been coupled with a torsionally stiff coupling but performance has suffered as a consequence of high radial stiffness.
The disadvantage of this is that any radial misalignment will causing premature wear to the coupling, the connected driveshaft and bearings.
The high flexibility in the Centaflex-KE coupling allows the necessary radial movement in the coupling to overcome all problems relating to misalignment, consequently increasing the lifespan of both the coupling and drive and reducing maintenance costs.
The Centaflex-KE coupling is designed as a compact single-piece element with an optional steel or high-performance plastic hub and provides a reliable and rust-proof connection to the toothed pump driveshaft.
It is designed with two pairs of flexible beams, similar to leaf springs, arranged at 90 degrees and it is this innovative beam configuration that provides the required radial movement.
The Centaflex-KE has undergone extensive testing in the field and results confirm the resilience of the plastic hubs and the longevity of the coupling.
It is compact, lightweight and competitively priced and is available with flywheel connections to SAE 6.5, 7.5, 8 and 10 and Centa produce hubs for every established driveshaft profile up to 400Nm.
