Product Details

KTR ROTEX® GR and GS Coupling Spiders are original elastomer elements designed for ROTEX® Jaw Couplingsby KTR Germany — a global leader in power transmission technology. These flexible spiders transmit torque reliably while damping vibration and compensating for misalignment between connected shafts. Widely used across industrial automation, pumps, compressors, and gear systems, KTR spiders ensure smooth, maintenance-free operation and long service life. The KTR ROTEX GR series is the standard spider design for general applications, while the KTR ROTEX GS series offers enhanced torsional stiffness and precision for servo drives and dynamic machinery. KTR ROTEX® GR Models: GR 7, GR 9, GR 14, GR 19, GR 24, GR 28, GR 38, GR 42, GR 48, GR 55, GR 60, GR 75, GR 90, GR 100, GR 110, GR 125, GR 140, GR 180, GR 200, GR 220, GR 250 KTR ROTEX® GS Models: GS 7, GS 9, GS 14, GS 19, GS 24, GS 28, GS 38, GS 42, GS 48, GS 55, GS 60, GS 75, GS 90, GS 100, GS 110, GS 125 KTR T-PUR® (Thermoplastic Polyurethane): Advanced polyurethane with up to 40% longer life and temperature resistance up to 120°C. Polyurethane (PU): Standard flexible elastomer for balanced torque damping. NBR (Nitrile Rubber): Ideal for vibration absorption low-noise applications. Hytrel®: For high dynamic performance elevated torque demand.
