ROTEX Spider Couplings – Sizes 75, 90, 100
The ROTEX 75, 90, and 100 spiders are heavy-duty elastomer inserts from KTR’s original ROTEX® coupling system, engineered for industrial pumps, compressors, gearboxes, and generator drives. These sizes are frequently used in continuous-duty applications where vibration damping, shock absorption, and precise torque transmission are critical for uptime and performance.
Constructed from high-grade elastomer, the spiders deliver reliable torsional flexibility, effectively compensating for angular, axial, and radial misalignment while minimizing noise and protecting connected equipment. Available in different Shore hardness options, they allow engineers to select the ideal balance between damping and stiffness for their drive.
These medium-to-large coupling sizes are commonly specified in:
🔹 Process industry equipment (pumps, agitators, compressors)
🔹 Marine and offshore auxiliaries
🔹 Power generation units (gensets, turbines, fans)
🔹 Heavy machinery and gear drives
Choosing OEM KTR ROTEX spiders ensures perfect compatibility, longer service life, and predictable performance — critical for avoiding costly failures caused by non-original inserts.
