Crossflex Disc Couplings

Crossflex couplings use disc packs (1) manufactured from stainless spring steel, as the driving flexible element. Steel hubs (2) are connected to the disc packs by a system of precision bushes (3) and high tensile bolts (4). This design provides a backlash free, torsionally stiff, all steel construction, which is maintenance free. The Crossflex coupling has modular components to enable adaption to a wide range of applications. Series 1 uses two hubs with a single disc pack. This series provides maximum torsional stiffness, but cannot compensate for radial misalignment. Series 2 incorporates a spacer (5) between two disc packs and two hubs. These compensate for radial as well as axial and angular misalignments. To reduce overall length, reversed hubs are available which fit inside of the central spacer. Both series can be supplied with shaft clamping elements to provide a totally backlash free drive.
