ROTEX® GS Compact is a clamping hub type with extremely short dimensions. It is shorter than the standard clamping hub by up to 1/3 and therefore particularly suitable for the use in narrow mounting spaces. 


Apart from the jaw-type geometry of the coupling hubs the zero backlash of the ROTEX® GS is mainly due to the geometry of the ROTEX® GS spiders. These are designed in a way that the convex teeth of the spider contact the concave jaws of the coupling hub under prestress. In combination with the straight toothing this results in a small surface pressure and an increased stiffness of the coupling system. 


The flexible spiders for the GS series are available in five different kinds of Shore hardness. The different kinds of Shore hardness allow to adjust ROTEX® GS easily to the individual conditions of an application with regard to torsional stiffness and vibration characteristics.

The flexible teeth are radially supported by a web on the inside diameter. In this way deformation caused by heavy acceleration or high speeds is prevented.

The permissible ambient temperature of the coupling depends on the Shore hardness of the spider.
