Simple and quick assembly and disassembly, complete freedom from maintenance and wear, absolutely backlash-free power transmission: Our Shaft Locking Assemblies (Shaft Clamping Elements, Shaft Power Lock, or Shaft-Hub Locking Device) are friction-locked shaft-hub connections manufactured to high quality standards. They are suitable for the precise fastening of all types of hubs, for example, toothed gears, running wheels and chain sprockets, levers, cam discs, belt and brake discs, slip-on gears, couplings or flanges, on shafts and axles. 


Compared to external clamping connections like shrink discs, 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 high torques but also axial and radial as well as bending loads to be transmitted reliably. Our Keyless Locking Assemblies are the superior alternative to conventional shrink-fits, wedge, keyway or polygonal connections and offer outstanding concentricity and resistance to alternating torsion. Our locking assemblies are available to users in various standard designs and sizes as well as customised special solutions.
