Cardan Shafts
Large SWC-BF Telescopic Flanged Cardan Shaft
Large SWC-BF Telescopic Flanged Cardan Shaft with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
Large SWC-BF is the flanged, telescopic member of the large SWC cardan-shaft range. Its table separates rated torque from fatigue torque and gives operating-angle and length-dependent dimensions, so the shaft should be checked against both the installed span and cyclic load rather than selected from diameter alone. The published model tables contain 7 size rows and provide torque values spanning 1400–8000 N·m, operating-angle values spanning 5–10 °. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Large-size telescopic shaft with a flanged connection
- Rated torque and fatigue torque are separate selection values
- Length and flange dimensions vary with the operating-angle condition
- The model data provides torque values spanning 1400–8000 N·m, operating-angle values spanning 5–10 ° for a traceable preliminary comparison.
Typical Selection Context
- Large rolling-mill or metallurgy drive lines with flanged interfaces
- Heavy equipment where a long span and controlled telescopic movement are required

Engineering Context
This model is best understood from its own construction: Large-size telescopic shaft with a flanged connection; Rated torque and fatigue torque are separate selection values; Length and flange dimensions vary with the operating-angle condition 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
- State installed length, telescopic travel and flange bolt pattern
- Compare rated/fatigue torque, operating angle, swing diameter and speed
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
Why are rated and fatigue torque both shown?
Rated torque describes the normal duty comparison; fatigue torque is needed when the load cycles repeatedly.
What must be checked around a large flanged shaft?
Check swing clearance, flange pilot and bolt circle together with installed length and operating angle.
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.
