Flexible Couplings
TL Flexible Sleeve Pin Coupling
TL Flexible Sleeve Pin Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
TL is a flexible sleeve-pin coupling with paired bore and bore-length arrangements. The table lists nominal torque, permissible speed, D/S/A dimensions and mass, while the sleeve and pins define the permitted movement. The shaft extensions and sleeve access should be checked before choosing between the Y/J/J1/Z arrangements. The published model tables contain 13 size rows and provide torque values spanning 6.3–16000 N·m, permissible-speed values spanning 1150–8800 r/min, bore values spanning 9–220 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: Flexible sleeve-pin construction; Paired bore and bore-length arrangements; D/S/A dimensions and mass by size 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
- Identify the correct Y/J/J1/Z bore arrangement and shaft extension
- Check torque, speed, D/S/A, displacement, temperature and access
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why does TL list several bore arrangements?
The arrangements suit different shaft extensions and hub positions; select from the drawing.
What is the sleeve maintenance consideration?
Allow space to inspect or replace the flexible sleeve and pins without removing unrelated equipment.
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.
