Cardan Shafts
SWC-WD Non-Telescopic Short Cardan Shaft
SWC-WD Non-Telescopic Short Cardan Shaft with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
SWC-WD is a non-telescopic short welded cardan shaft for a fixed-length angled connection. The table gives swing diameter, rated torque, fatigue torque, operating angle and fixed dimensions, so selection is primarily an exercise in matching the existing shaft span and clearance to the cyclic load. The published model tables contain 11 size rows and provide torque values spanning 12.5–1000 N·m, operating-angle values spanning 15–25 °. Use those values for preliminary comparison only; final materials, current standards, manufacturing details and operating suitability require confirmation from RONGXING DRIVE.
Key Features
- Short fixed-length welded cardan shaft
- Operating angle and fatigue torque are explicit table fields
- Drawing controls the welded-end and bolt details
- The model data provides torque values spanning 12.5–1000 N·m, operating-angle values spanning 15–25 ° for a traceable preliminary comparison.
Typical Selection Context
- Short fixed-span drives in rolling and heavy process machinery
- Welded cardan connections where no telescopic travel is required

Engineering Context
This model is best understood from its own construction: Short fixed-length welded cardan shaft; Operating angle and fatigue torque are explicit table fields; Drawing controls the welded-end and bolt details 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
- Confirm fixed length, angle, phasing and surrounding guard clearance
- Compare swing diameter, rated torque, fatigue torque and speed
- Send the exact model row, assembly drawing and actual duty data with the inquiry.
Product FAQ
When should a non-telescopic shaft be considered?
Use it when the equipment geometry defines a stable shaft span and no length compensation is needed.
Why is fatigue torque important on a short shaft?
Short length does not remove repeated-load effects; cyclic torque still needs a fatigue comparison.
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.
