Synchro-Link® STS TL® Timing Belt Pulleys

Synchro-Link® STS TL construction

The type of pulley used on a Synchro-Link® drive depends on a number of factors, including but not limited to, space available, ratios, center distances, horsepower being transmitted, speeds, and user preference of mounting systems (i.e. QD®, TL® or Minimum Plain Bore).

With Synchro-Link® Drives, as with gear or chain drives, circular pitch (usually referred to as pitch) is a fundamental consideration. On the belt, pitch is the distance between tooth centers and is measured on the pitch line of the belt. On the pulley, pitch is the distance between groove centers and is measured on the pulley’s pitch curve.

The pitch line of a Synchro-Link® Drive Belt is located within the tension member. The pitch circle of a Synchro-Link® Drive Belt pulley coincides with the pitch line of the belt mating with it.

Any Synchro-Link® Drive Belt must be run with pulleys of the same pitch. A belt of one pitch cannot be used successfully with pulleys of a different pitch.
