Application Notes:
A range of plastic injection moulded shaft couplings giving high torsional stiffness combined with exceptional durability to shaft misalignment. There are two basic designs called UJ and GJ. Type UJ is for lighter usage and smaller angular and parallel shaft offsets, whilst type GJ, with its two flexible elements, is ideal for medium usage.
