Rexnord 10287352 ES20 Precision Coupling Element

Rexnord Omega ES20 Element, 10287352, is a spacer-style elastomeric coupling element designed for Rexnord Omega ES20 couplings to transmit torque between shafts while absorbing shock, damping vibration, and accommodating angular and parallel misalignment in industrial drive trains. It features a urethane (orange) elastomer shoe, standard imperial cap screws, and a standard shoe coating, and it is specified for high‑misalignment service with a continuous torque rating of 2300 in-lbs (260 Nm) and a maximum speed of 4800 rpm. Dimensions for the ES20 element include a major diameter of 7.25 in (184 mm); width and length of 7.50 in; height of 9.75 in; and a net weight of 6.59 lb, offering a compact footprint for mid‑power applications. The element is listed as Elastomeric, with an Element Style of High Misalignment, and not assembled with high speed rings. MFG: Omega; ES20 ELEMENT is part of Rexnord's Omega spacer elastomeric family, designed to work with ES20-sized hubs in spacer assemblies, with variants available such as ES20 elements with stainless hardware and alternative materials within the ES20 family.
