ROTEX® GS is one out of three coupling types which KTR offers in the range of backlash-free shaft couplings. The particular benefits of this design are the easy assembly and the high power density. KTR offers ROTEX® GS Compact as a low-cost design of the GS series. This backlash-free shaft coupling can be up to one third shorter than the standard ROTEX® GS and is offered with axial cut from size 24. Subject to its symmetrical arrangement ROTEX® GS Compact has a higher balancing quality compared to usual clamping hubs.
