Good Connections Thanks to Quality

FLENDER GKG® cardan couplings are elastic, double-jointed output couplings designed to compensate for primary suspension misalignments in bogies, enabling full torque transmission between the gear unit and the powered wheel set shaft. They allow for very large shaft displacements and significant misalignments between the axle and the gear unit, while generating only minimal reaction forces.

The components of the FLENDER GKG coupling can be installed individually on both the gear unit and the wheel set shaft. These coupling parts are equipped with pre-installed, self-calibrated spherical bearings that feature protected rubber elements. These elements boast an extended service life of up to one million kilometers of vehicle travel. By screwing the brackets onto the spherical bearing pins, the coupling can be easily installed using standard tools, and the spacer automatically centers itself.
