ROTEX® Clamping hub / DH / KTR Systems

ROTEX clamping hub type DHwith feather keyway for double-cardanic connectionPositive-locking power transmission with additional frictionfit for radial assembly of coupling. The friction fit avoids orreduces reverse backlash. Surface pressure of the keywayconnection is reduced.ROTEX® flexible jaw couplings - types of hubs:Since ROTEX® is used on many different applications and mounting conditions, this coupling system is available with various hub types.These types mainly differ in that they provide either positive or frictionally engaged (backlash-free) connections, but mounting situations like, for example, gear shafts with integrated transmission cams or similar applications are covered, too.
