gear couplings / curved-tooth gear couplings

Our torsionally stiff gear couplings operate according to the curved-tooth gear principle. As a result edge pressure in the spline is avoided with angular and radial displacements by the gear coupling.
BoWex curved-tooth gear couplings with the material combination of steel hubs and polyamide sleeves allow for maintenance-free permanent operation with severely beneficial coefficients of friction of the teeth.

GEARex all-steel gear couplings with grease lubrication and O-ring seals comply with the international standard. Permanent grease lubrication generates good friction ratio of the spline with almost wear-free operation and a high service life expectation of the coupling.

Subject to their double-cardanic operating principle both BoWex gear couplings and GEARex all-steel gear couplings are particularly suitable for offsetting axial, radial and angular shaft displacements.
