Wind turbines are commonly equipped with splined or keyed shafts, however, many operators find that these methods of connection are too complex and expensive.

In addition, when using a key or spline, parts must be aligned precisely, whereas a shrink disc allows for minor misalignment.
All Tollok shrink discs have been designed to fit all types of hubs onto shafts and axles, replacing traditional shrink fits, keys and polygon connections, and splined shafts.
