Backlash Free Servo Couplings

KTR’s range of backlash free servo couplings are designed for unrivalled performance and expertise in motion control applications. Giving you complete resistance to vibration and shock, zero backlash coupling is the must have coupling for applications which need precision in your motion control.

Zero backlash couplings maintain the same relationship between the input and output shaft without any lost motion. With a low windup, the coupling gives precise motion control and accuracy without any positioning errors.

ROTEX® GS is a three-part coupling, backlash-free under pre-stress. The different hub designs and the different Shore hardnesses offer the optimal coupling for each application in automation engineering. In spite of its vibration-damping characteristics it is torsionally stiff so that it is not necessary to make any concessions to accuracy even with highly dynamic servo drives. The ROTEX GS works with the modular system; a high variety of different hub designs is available which can be combined within one coupling size.

We supply the full range of KTR backlash free servo couplings and our technical sales team can advise you & select the correct coupling for your application. Whether you have a failure or performance issue with your existing coupling and drive arrangement or if you are an OEM looking at a new design you can draw on our expertise to support you at every turn.

Our machine shop can bore and keyway the coupling as required and we can also repair and rebuild the gearmotor that it is fitted to or supply a replacement as necessary. Couplings often fail due to excessive vibration levels and our in-house dynamic balancing machine will remedy that as we can balance whatever it is fitted to.
