Locking Assemblies are installed between shaft and hub. By tightening the clamping screws, inner and outer rings press themselves onto the contact surfaces of the components to be connected, thus creating a friction-fit press connection. This allows not only the highest torques but also axial and radial as well as bending loads to be transmitted reliably. Locking Assemblies are the superior alternative to conventional shrink-fits, wedge, keyway or polygonal connections.
