Type ASK Patented, Sliced Coupling – with Customizable Dimension Options
Product Description
The ASK sliced coupling is the ideal tool for equalizing all kinds of offset. Its unique slit structure represents the perfect solution for misaligned shafts or installation situations involving high levels of resonance.
But the benefits of the parallel slit levels are not restricted to resonance damping: The ASK type series is also ideally suited to applications involving frequent load changes, even during reversing duty.
Another standout feature of this coupling is its one-part, compact design. The resulting high torsional stiffness and true running accuracy create excellent rotational characteristics that enable high speeds to be achieved. Thanks to the simple assembly method, which can be performed in a matter of seconds using just a single DIN 911 tool, couplings of this type can be incorporated into any drive train.
ASK sliced couplings from the standard range are suitable for shaft diameters ranging from 4 to 60 mm. However, we also offer a large number of special designs that allow you to choose from a wide range of fastening options – from the standard clamping hub connection, grub screw fastening on the shaft, spread hubs for hollow shafts, half-shell designs, and thread shaft connections, right through to VMA clamping device fastening methods that are suitable for larger diameters and ensure completely backlash-free power transmission.
Sliced couplings can be used in a varied range of applications. Their technology can be adapted to meet customer-specific requirements.
