Product Structure

1. Integral Forged Fork Head – One-piece forged construction without bolt connections – eliminates the weak point found in welded or bolted designs, dramatically improving reliability and service life.

2. Cross Shaft Bearing Bores – Precision-machined bearing holes (75×152.5mm) for accurate cross shaft fit and extended bearing life.

3. Flange Mounting Surface – Precision-ground flange face with 8×M17 bolt holes for secure flange connection.

4. Keyway 28×8mm – Precision-machined keyway for positive torque transmission.

5. 40Cr Alloy Steel – High-strength material with quenched & tempered heat treatment (HB250-300) for superior wear resistance and fatigue strength.

💡 How it works: The SWC180 flange yoke serves as the critical connection point between the cardan shaft cross shaft and the driven equipment flange. The integral forged design transfers torque from the cross shaft through the fork arms to the flange mounting face. The 40Cr material with quenched & tempered heat treatment provides the strength to withstand heavy shock loads, while the precision-machined bearing bores ensure smooth rotation and long service life. The 8×M17 bolt pattern securely mounts the yoke to mating flanges in mining, metallurgical, and heavy industrial drive systems.
