The Candy Timing Hub is the low cost phase adjusting coupling designed for precise rotary positioning. While in motion, the Timing Hub operates as a rigid shaft coupling. In the static position, it is possible to relocate one of the Timing Hub's flanges relative to the other, thus changing the rotary position of the output element. When both flanges are secured with the use of drive bolts, the Timing Hub again operates as a rigid shaft coupling.

The ability to advance and retard the position of various machine components is too often accomplished by friction-type clamping mechanisms. Such methods often slip under moderate shock loads, resulting in unnecessary and costly downtime. The Timing Hub eliminates the need for such devices, offering the most economical means of positive position control.
