ROTEX GS backlash-free servo couplings

ROTEX GS is a three-part servo coupling backlash-free under prestress (elastomer coupling). The various hub versions and different Shore hardnesses determine the optimum coupling for each application in automation technology.

This servo coupling is applied wherever drives need to position precisely. In spite of its 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 CHINAMFG GS backlash-free elastomer couplings allow for simultaneous compensation of radial, axial and angular displacements. The backlash-free servo coupling CHINAMFG GS uses the construction kit system, it is available in a high variance of different hub types which can be combined within 1 coupling size.

The selection of the hub material depends on the size and it is composed of either aluminium or steel. Both frictionally engaged connections without feather keyway and positive-locking connections with feather keyway are available.

KTR distributes a new spider considerably increasing the performance level of the backlash-free servo coupling type CHINAMFG GS with regard to temperature resistance and pressure resistance. The material is a newly developed “thermoplastic polyurethane” with the hardness degree „52 Shore D” and a temperature resistance up to 120 °C. Main applications are servo hydraulics and test bench technology.

Applications of the servo coupling CHINAMFG GS:
