Cardan Shafts
SWC-WH Non-Telescopic Welded Cardan Shaft
SWC-WH Non-Telescopic Welded Cardan Shaft with model-specific technical data, engineering context and assembly drawing for preliminary selection.
Product Overview
SWC-WH is a non-telescopic welded cardan shaft with a fixed installed geometry. Its model rows combine swing diameter, rated and fatigue torque, operating angle and welded-end dimensions. The absence of telescopic travel makes accurate shaft-span measurement and phasing especially important before a size is requested. The published model tables contain 13 size rows and provide torque values spanning 1.25–710 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.
Key Features
- Fixed-length welded cardan-shaft configuration
- Rated and fatigue torque support normal and cyclic-duty review
- Operating angle and swing diameter are drawing-linked
- The model data provides torque values spanning 1.25–710 N·m, operating-angle values spanning 15–25 ° for a traceable preliminary comparison.
Typical Selection Context
- Fixed-span welded drive lines for rolling and process equipment
- Angled shaft connections where compact fixed geometry is preferred

Engineering Context
This model is best understood from its own construction: Fixed-length welded cardan-shaft configuration; Rated and fatigue torque support normal and cyclic-duty review; Operating angle and swing diameter are drawing-linked Industry selection practice checks torque and speed together with the movement, shaft interface, installation envelope and maintenance conditions allowed by that construction.

Product FAQ
What is the main installation constraint for SWC-WH?
The fixed shaft length must match the machine span while preserving angle and guard clearance.
What should be sent with a WH inquiry?
Send the drawing interface, installed length, operating angle, speed and torque duty.
