ROTEX® Clamping hubs

0 - 4,500 Nm / torsionally flexible jaw coupling with clamping hubs

Jaw coupling with clamping hubs for spline bores acc. to DIN and SAE

ROTEX clamping hubs are torsionally flexible elastomer couplings with clamping hubs and particularly suitable for applications with reversing operation.

Our clamping couplings are provided with spline bores acc. to DIN and SAE as a standard (for standard splines see catalogue). Clamping, i. e. axial fastening of the hub, is realised via cap screws.

Easy assembly and disassembly of the hubs of this clamping coupling.


  • fail-safe clamping coupling (clamping hubs)

  • standard hub material steel

  • suitable in combination with spline bores acc. to DIN 5480, DIN 5482, SAE J498 as well as DIN 9611 / ISO 500 (p. t. o. shaft), DIN 5463 (ISO 14), DIN 5481 and DIN 5472

  • balanced based on 3D-CAD data

  • particularly suitable for applications with reversing operation
