The KTR Rotex Spider GS-Series for Servo Application is a high-precision, backlash-free elastomer coupling designed specifically for servo drives in automation technology. Featuring a three-part construction, the ROTEX GS coupling efficiently damps vibrations while maintaining torsional stiffness, ensuring absolute accuracy for positioning tasks. Its design allows simultaneous compensation for radial, axial, and angular misalignments, making it ideal for highly dynamic servo drive systems. The modular construction kit system offers a wide variety of hub types with different Shore hardness elastomer spiders, providing an optimized coupling solution tailored to specific application needs. Hubs are available in either aluminum or steel, with frictionally engaged connections without keyways or positive-locking feather keyway options, enabling flexible installation and secure torque transmission. This coupling excels in scenarios requiring precise drive positioning combined with reliability and vibration reduction, making it a superior choice in automation and servo engineering applications.

ROTEX GS is a three-part servo coupling (elastomer coupling) backlash-free under prestress. The different hub types and various kinds of Shore hardness provide the optimum coupling for every application in automation technology.
It is used wherever drives have to be positioned accurately. Despite their vibration-damping properties, the coupling is torsionally stiff so that you do not have to cut back on precision even with highly dynamic servo drives. The ROTEX GS backlash-free elastomer couplings allow for simultaneous compensation of radial, axial, and angular displacements.
The backlash-free servo coupling ROTEX GS uses the construction kit system, it is available in a high variance of different hub types which can be combined within one coupling size.
The choice of the hub material depends on the size and the hub is either made of aluminium or steel. Both frictionally engaged connections without feather keyways and positive-locking connections with feather keyways are available.
