KTR ROTEX GS Compact Design Coupling - Aluminium Hub, Polyurethane Insert

Product Details

⭐ KTR ROTEX GS Compact Design 2.8 – Backlash-Free Shaft Couplings The KTR ROTEX GS Compact design 2.8 is a high-precision, backlash-free elastomer coupling developed for servo drives, CNC machines, robotics, linear motion systems, automation equipment, and high-speed positioning applications. This compact version is engineered to be up to one-third shorter than standard jaw couplings while delivering higher power density, improved concentricity, and smooth, uniform torque transmission. The slot-less cam geometry ensures excellent balance for high-speed servo operations and vibration-free running under dynamic load. The ROTEX GS Compact design 2.8 uses high-quality polyurethane spiders available in 80 Sh-A, 92 Sh-A, 98 Sh-A and 64 Sh-D hardness grades, making it suitable for precision motion control, torque-controlled applications, and sensitive servo-motor installations requiring zero-backlash performance.  ROTEX GS Compact Design 2.8 The following models are available in the compact 2.8 configuration: GS 7 Compact design 2.8GS 8 Compact design 2.8GS 9 Compact design 2.8GS 12 Compact design 2.8GS 13 Compact design 2.8GS 14 Compact design 2.8GS 16 Compact design 2.8GS 19 Compact design 2.8GS 24 Compact design 2.8GS 28 Compact design 2.8GS 38 Compact design 2.8 These sizes cover a wide torque range suitable for both light-duty and heavy-duty servo applications. 🧱  MOC Hubs: Aluminium or steel depending on size and application Spider (Elastomer): High-performance polyurethane (PU) in multiple hardness grades Clamping Hub Option: Design 2.8 (without keyway) or design 2.9 (with keyway) Finish Bore: ISO H7 tolerance Keyway (optional): DIN 6885, JS9 fit   ⚙️ Key Features of ROTEX GS Compact Design 2.8 Backlash-free operation for accurate servo positioning Compact form factor for reduced installation length High power density for demanding torque transmission Excellent dynamic balancing and concentricity Torsionally flexible elastomer for damping and shock absorption Smooth torque transfer with slot-less cam geometry Suitable for high-speed and reversing drives ATEX-approved designs available for hazardous applications 🌍 Applications of ROTEX GS Compact Design 2.8 Widely used in industries requiring precise, dynamic, and smooth torque transmission: Servo motors & stepper motors CNC machines and machining centers Robotics & automation systems Packaging machinery Printing and converting machines Pharmaceutical and food-processing equipment Linear actuators, ball-screw drives, and gantry systems Measuring devices, encoders, inspection machines High-speed spindles and indexing equipment Rotex GS compact design 2.8 Backlash free coupling Servo motor coupling Zero backlash shaft coupling Polyurethane spider coupling High precision servo coupling CNC coupling KTR Rotex elastomer coupling Flexible shaft coupling for automation Servo drive torque coupling
