Product Description
SWC-WD Heavy Duty Universal Joint Drive Shaft Assembly – High Torque Cardan Shaft Coupling with Flange
The SWC-WD universal joint drive shaft is a non-telescopic short-type cardan shaft coupling engineered for heavy-duty industrial power transmission. Designed with a compact structure and high angular compensation capability, this SWC-WD heavy duty drive shaft delivers exceptional torque transmission efficiency for demanding applications across cranes, mining, marine, and heavy machinery industries.
Manufactured from premium forged steel with precision automated welding, our SWC-WD cardan shaft offers a reliable, cost-effective alternative to imported universal joint assemblies. With bore diameters ranging from 100mm to 620mm and rated torque capacity from 1.25 kN·m to 1000 kN·m, the SWC-WD flange drive shaft ensures stable operation even at high rotational speeds and shaft misalignment angles of 15° to 25°.

✅ Premium Forged Steel Construction
- 45# forged steel yoke and flange for impact resistance
- 35CrMo alloy steel welded fork ends for enhanced fatigue strength
- 20CrMnTi cross bearings and multi-row needle rollers for extended service life
✅ Automated Welding & Precision Machining
Fork joints utilize robotic automated welding instead of manual welding, ensuring consistent penetration, zero porosity, and superior crack resistance under cyclic loading.

FAQ – SWC-WD Universal Joint Drive Shaft
Q1: What is the difference between SWC-WD and SWC-WH type?
A: SWC-WD is the non-telescopic short type with fixed length, offering higher rigidity and compact design. SWC-WH is the welded hub long type with telescopic adjustment. Choose WD for space-constrained, high-torque applications.
