Rexnord Tollok Shrink Disc - TLK681 420x670

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

Shrink discs provide many advantages over keyway and splined shafts. The design is more compact and lightweight, the cost of ownership is reduced and there is less maintenance required. 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.
