Based on the operating principle of the renowned crowned gear, edge pressure in the spline is avoided with angular and radial displacements. In addition the permanent lubrication generates beneficial friction conditions of the spline with almost wear-free operation, combined with a high service life expectation of the coupling.

To assure regular and monitored lubrication when mounted, there are two opposite hydraulic connections radially on every coupling sleeve, thus four connections offset to each other by 90° with a complete GEARex gear coupling.

The interior space of the coupling is sealed via O-rings (NBR 70 ShA). The feather keyways must be sealed against escape of lubricant with assembly.
