This section will allow you to select controlflex inserts to be used individually or as part of an assembly. The unique design of the insert allows them to remain rigid while flexing under misalignment conditions. Controlflex inserts have low restoring forces and help protective sensitive system components such as bearings in encoder type applications. They come standard with a center hole allowing shafts to be penetrated through the center if the application requires it. Controlflex inserts are manufactured from acetal and are designed as the wear element making replacement simple and cost effective.
