Ktr Rotex Gr Coupling

The KTR ROTEX® Spider / Elastomer Insert is the central flexible element of the renowned KTR Rotex Jaw Coupling system, designed to transmit torque smoothly while damping torsional vibrations and absorbing shocks. Manufactured from high-quality Polyurethane (PU) elastomers, these inserts ensure zero backlash, long service life, and silent power transmission. At Jobwurx Industrial Ventures Pvt. Ltd., we supply the complete range of KTR Rotex Coupling Spiders for GR and GS series couplings — available in various hardness grades (Shore A 92, 98, 64) and sizes from GR 7 to GR 200. These spiders fit precisely between two coupling hubs, maintaining alignment and compensating for shaft misalignments under high-speed and dynamic load conditions. Available Models and Sizes: KTR Rotex Spider Sizes (Standard Range):GR 7, GR 9, GR 14, GR 19, GR 24, GR 28, GR 38, GR 42, GR 48, GR 55, GR 60, GR 65, GR 75, GR 90, GR 100, GR 110, GR 125, GR 140, GR 160, GR 180, GR 200 Compatible Hub Types: 1a/1a, 1a/1b, 1b/1bOperating Temperature: -40°C to +100°C (up to +120°C for special grades)Torque Range: Up to 12,000 Nm Material & Hardness 1. Polyurethane (PU) Elastomer – Standard Spider Materials: 98 Shore A (Red): High stiffness, high torque transmission, minimal damping – suitable for dynamic servo drives precision motion control. 92 Shore A (Yellow): Balanced performance for general industrial use – offers excellent flexibility vibration damping. 64 Shore D (Green): Extra stiff material for heavy-duty high-speed applications requiring low torsional flexibility. 2. Thermoplastic Polyurethane (TPU):Offers improved wear resistance, temperature stability oil resistance. 3. Electrically Conductive and ATEX-rated Elastomers:For explosive hazardous environments (compliant with EU Directive 94/9/EG). Advantages: Torsionally flexible fail-safe operation High torque transmission compact dimensions Maintenance-free easy to replace without dismantling hubs Excellent damping of torsional vibrations shocks Compensates for misalignments: axial, radial, angular Zero backlash when preloaded for precision drives Available in standard, high-temperature, conductive variants Long operational life due to optimized tooth geometry and precision PU material Interchangeable with global brands like Lovejoy, Ruland, Mayr, Fenner jaw couplings KTR Rotex Spider, Rotex PU Spider, KTR Elastomer Insert, Rotex Coupling Spider, KTR GR Spider Element, Rotex Coupling Element, Jaw Coupling Spider, Flexible Coupling Insert, Polyurethane Coupling Spider, KTR GR Series Spider, KTR Rotex GS Spider, Flexible PU Element for Rotex Coupling, KTR Jaw Coupling Spare, Rotex GR Elastomer, KTR Rotex Element Supplier, Rotex GR 14 Spider, Rotex GR 19 Spider, Rotex GR 24 Spider, Rotex GR 38 Spider, Rotex GR 48 Spider, Rotex GR 75 Spider, KTR Rotex Replacement Element, Industrial Coupling Spider, KTR Rotex Coupling India, Jobwurx Industrial Ventures Pvt.
