Slot couplings - Highlights

The ASK slot coupling is a solution for equalizing all kinds of offset. Its unique slit structure once revolutionized the coupling industry – over the years, this well established solution has come a long way and now represents the ideal solution for installation situations that involve misalignment or high levels of resonance. Not only does the one-part design ensure absolute stability at the highest speeds (>30,000 rpm) and a low mass moment of inertia, but it also enables maximum torsional stiffness to be achieved in the face of dynamic load changes.
