ROTEX® GS Couplings
The ROTEX® GS couplings by KTR transmit torque with torsionally flexible backlash from curved jaw hubs and elastomeric elements. This allows for misalignment and for functionality when misaligned, minimizing of restoring forces, dampen shock and vibration, and while creating a zero-backlash torque transmission. The ROTEX® GS couplings not only provide torsional stiffness, they also provide dampening to the system. Interlocking curved jaws allow up to 3.625 inches and a maximum nominal torque of 21,242 (in-lb) and while accommodating blind assembly.

Our KTR couplings are "LTSOH" (Limited to Stock on Hand) and will no longer be available after the current stock has been depleted.
