Rigid & Special Couplings
YL Flange Coupling
YL Flange Coupling with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
YL is a flange coupling with a broad model table covering torque, speed, bore, bore length, D/D1, b/S/b1, bolt diameter and bolt count, inertia and mass. The flange and bolt-circle data make alignment and fastener access central to the selection; unlike a flexible element coupling, the machine must control shaft alignment. The published model tables contain 10 size rows and provide torque values spanning 63–100000 N·m, permissible-speed values spanning 1200–6300 r/min, bore values spanning 22–250 mm. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Flanged rigid connection with bolt-circle data
- Bore, flange thickness and bolt dimensions by model
- Inertia and mass support rotating-assembly review
- The model data provides torque values spanning 63–100000 N·m, permissible-speed values spanning 1200–6300 r/min, bore values spanning 22–250 mm for a traceable preliminary comparison.
Typical Selection Context
- Rigid motor, gearbox and process-shaft connections
- Equipment with accurately aligned flange faces and accessible fasteners

Engineering Context
This model is best understood from its own construction: Flanged rigid connection with bolt-circle data; Bore, flange thickness and bolt dimensions by model; Inertia and mass support rotating-assembly review 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
- Match bore, flange thickness, bolt diameter/count and shaft span
- Confirm alignment, runout, speed, torque, guard and maintenance access
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
What is the main YL installation requirement?
The two flange faces and shaft axes must be aligned within the confirmed assembly limits.
Why are bolt dimensions listed separately?
Fastener size and count affect the flange interface and must match the machine connection.
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.
