Flexible Couplings
XL Star Elastomer Coupling
XL Star Elastomer Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
XL is a star elastomer coupling with a compact jaw-and-spider interface. The model record is intended to be read with its assembly drawing for bore, length, clearance and element details; the elastomer transmits torque while accommodating the specified movement. Confirm spider material and temperature for the actual duty. The published model tables contain 16 size rows and provide torque values spanning 34–35000 N·m, permissible-speed values spanning 1800–19000 r/min, bore values spanning 6–220 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.

Engineering Context
This model is best understood from its own construction: Star elastomer element between coupling jaws; Compact installation and replaceable element concept; Bore and clearance details are drawing-specific Industry selection practice checks torque and speed together with the movement, shaft interface, installation envelope and maintenance conditions allowed by that construction.
Technical Notes
- Model symbols, units and empty or placeholder cells are shown as published.
- Dimension letters must be interpreted with the relevant assembly drawing.
- Published values support preliminary review and do not replace final engineering confirmation.
Assembly Drawing
Information Required for Selection

Product FAQ
What does “star” refer to?
It identifies the elastomeric spider element positioned between the coupling jaws.
Can any spider material be used?
No. Material and temperature suitability must be confirmed for the operating environment.
Are the published values final ordering values?
No. They are preliminary engineering data; confirm the selected model, drawing, dimensions, materials, standard and suitability with RONGXING DRIVE.
Technical data is provided for preliminary selection. Confirm the final model, dimensions, materials, applicable standard and operating suitability with RONGXING DRIVE before quotation, manufacture or installation.
