Backlash-free servo coupling (hollow shaft coupling) for hollow shafts
ROTEX GS expansion hubs (hollow shaft coupling) are used when torques have to be transmitted through a hollow shaft, e. g. applications with short shaft distances or narrow mounting conditions.
With this hollow shaft coupling the easy, safe and frictionally engaged shaft-hub-connection is generated via a centric screw. The hubs are made of aluminium and the expansion mandrel is made of steel.
