Compact power transmission with ROTEX spiders – Sizes 28, 38, 42
The ROTEX 28, 38, and 42 spider inserts are medium-size coupling elements designed for industrial drives, hydraulic pumps, compressors, and gear units. Built from high-performance elastomer, these spiders provide reliable torsional vibration damping, compensate for shaft misalignment, and protect connected equipment from shock loads.
These sizes are often selected for mid-range electric motor drives where compact dimensions and long service life are essential. As part of the original KTR ROTEX® coupling system, spiders are available in multiple Shore hardness options, making it possible to match specific operating conditions.
Choosing OEM KTR spiders guarantees correct fit, stable performance, and avoids premature wear caused by non-original copies.
