Cardan Shafts
SWC-CH Long Telescopic Welded Cardan Shaft
SWC-CH Long Telescopic Welded Cardan Shaft with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
SWC-CH is the long telescopic welded cardan shaft for a welded-end arrangement. The model data is centered on swing diameter, rated and fatigue torque, angle, telescopic compensation and minimum length, while the drawing defines the welded connection details. Its long configuration should be reviewed for torsional duty and surrounding guard clearance. The published model tables contain 20 size rows and provide torque values spanning 12.5–710 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.

Product FAQ
Why does the long CH version need envelope review?
The longer shaft span increases the importance of minimum length, swing clearance and support geometry.
Which drawing information should accompany an inquiry?
Send the end connection, phasing and installed-length information shown by the assembly drawing.
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.
