The center disc of the Offset Coupling is supported by 3 or more links on either side, which allows for its large misalignment range.Within the allowable offset range, the angle between these links defines the position of the center disc and provides proper support and stability for it.As you approach zero parallel misalignment, or to the Offset Coupling’s full parallel misalignment rating, the angle between the links is compromised, they do not properly support the center disc, and reaction loads on the connected components are greatly increased in this condition.Strict adherence to the minimum and maximum parallel misalignment ratings listed in the catalog will ensure smooth operation of the Offset Coupling without inducing any sideloads or reaction loads on the connected components.
