Product Structure & Components
Integral Forged Fork Head – One-piece construction without bolt connections – eliminates the most common failure point in traditional universal joints. The SWC series uses an integral fork structure where bearings are fixed without bolts, avoiding loose bolt breakage and simplifying maintenance.
Cross Shaft Assembly (Spider) – Precision cross shaft with multi-row needle roller bearings for high wear resistance and strength. Equipped with grease fittings for easy lubrication. Cross shaft dimensions: 120×275mm.
Telescopic Welded Shaft – Standard telescopic design with 140mm stroke compensates for axial displacement.
60-Tooth Face Flange Connection – Features precisely machined interlocking teeth on the flange face (60 teeth) for accurate alignment and secure torque transmission under severe shock loads and reversing operations.
Alloy Steel Construction – 42CrMo or 40Cr with quenching process – high strength and durability. Raw blanks are refined via quenching and tempering, while spline shafts undergo intensive induction hardening.
💡 How it works: The SWC315BH cardan shaft uses an integral fork head design that eliminates the weak link of bolt compression bearing seats, completely avoiding common malignant damage caused by bolt loosening or breaking. Torque is transmitted through the cross shaft, while the telescopic shaft accommodates axial displacement. The 60-tooth face flange connection provides superior alignment and torque transmission under heavy loads. The integral fork design provides 30-50% longer service life than bolt-connected designs.
Face-Tooth Flange Connection – Technical Advantages
The SWC315BH features a 60-tooth face flange, which offers several critical advantages over standard bolted flanges for heavy-duty applications:
| Feature | Face-Tooth Flange (SWC315BH) | Standard Bolt Flange |
|---|---|---|
| Torque Transmission | Through interlocking teeth – positive drive | Through bolt preload – friction-dependent |
| Alignment Accuracy | Superior – teeth ensure precise centering | Moderate – relies on bolt fit |
| Impact Resistance | Excellent – teeth absorb shock loads | Limited – bolts can loosen under shock |
| Reversing Operation | Stable – no backlash in tooth engagement | Can experience bolt loosening |
| Maintenance | Reduced – no frequent bolt re-torquing | Frequent bolt inspection required |
| Load Capacity | Higher – uniform load distribution | Lower – concentrated at bolt points |
✅ The 60-tooth face flange with 12-bolt pattern is the preferred connection for the most demanding heavy-load applications such as large rolling mills, ship propulsion systems, and heavy crane main drives.
