Product Structure & Components
Integral Forged Fork Head – One-piece construction without bolt connections – eliminates bolt loosening and breakage, 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 (注油孔) for easy lubrication . Cross shaft dimensions: 55×128mm.
Telescopic Welded Shaft – Standard telescopic design with 80mm stroke compensates for axial displacement.
Flange Connection – 130mm outer diameter flange with 8 holes evenly distributed at 13mm diameter for secure mounting .
Alloy Steel Construction – 42CrMo or 35CrMo 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 SWC150BH 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 8-bolt flange connection provides secure mounting to driven equipment. The integral fork design provides 30-50% longer service life than bolt-connected designs .
