SWC Heavy-Duty Telescopic Cardan Shaft Universal Coupling (Flange Connection)

High-Torque Cross Shaft Drive Shaft | Axial Compensation & Integral Fork Design

The SWC Series Heavy-Duty Universal Joint Coupling (Cardan Shaft) is engineered for high-torque industrial power transmission applications requiring large angular compensation and smooth telescopic length adjustments. Manufactured with an integral yoked structure using high-grade forged steel (45# steel hubs, 35CrMo welded flange yokes, and 20CrMnTi alloy cross journal bearings), this series handles nominal torques ranging from 1.25 kN·m to 1,000 kN·m with rotation swing diameters from 100 mm to 620 mm. Featuring automated robotic welding, multi-row needle roller bearings, and grease lubrication ports, it provides robust and long-lasting shaft transmission for heavy machinery.

Key Advantages & Features

• Integral Yoke Design for High Safety: One-piece forged fork structure eliminates structural weak points, providing high operational reliability and fracture resistance under extreme dynamic loads.
• High-Strength Alloy Materials: Utilizes premium 45# forged steel hubs, 35CrMo flange-welded yokes, 42CrMo alloy components, and 20CrMnTi hardened cross-journal bearings for maximum impact toughness and fatigue life.
• Automated Precision Welding: Shaft joints are welded using high-precision automated welding processes, ensuring uniform bead quality, zero cracking risks, and high torsional strength.
• Telescopic Spline with Axial Compensation: Quenched cold-rolled seamless steel spline shaft provides smooth axial movement, tight clearances, and long-term wear resistance.
• Multi-Row Needle Bearings & Easy Maintenance: Cross journals feature wear-resistant multi-row needle bearings equipped with dedicated grease nipple ports for fast and convenient lubrication.
• Large Axis Angle Compensation: Operates efficiently across shaft deflection angles ranging from 15° to 25°.
