SWC Series Truck Transmission Universal Joint Drive Shaft Coupling

Heavy-Duty Cardan Shaft with Square Flange & Integral Fork Head Structure

The SWC Series Universal Joint Cardan Drive Shaft Coupling is a high-torque, heavy-duty mechanical transmission solution designed for commercial truck drivelines, industrial rolling mills, heavy construction machinery, and mining equipment. Built with high-strength S45C forged steel hubs, premium 42CrMo alloy steel needle bearings, and a robust integral fork head cross design, this Cardan shaft features a square flange interface that ensures reliable power transfer under large angular misalignments (15° to 35°). Offering outstanding transmission efficiency up to 99.8%, smooth operation, and high shock load resistance, the SWC series is engineered for demanding rotational applications.

Key Advantages & Features

• Integral Fork Head Construction: SWC-type integral fork head design significantly improves structural rigidity and reliability compared to split-fork configurations, handling higher torque loads in space-constrained layouts.
• Large Angle Compensation Capability: Accommodates operating axis angles from 15° to 25° (up to 35° maximum operating angle), providing smooth power transmission across misaligned shafts.
• High Power Transmission Efficiency: Delivers exceptional energy efficiency (98% – 99.8%), making it an ideal choice for continuous heavy-duty industrial and vehicle drivelines.
• Heavy-Duty Alloy Components: Built with S45C carbon steel body hubs and high-grade 42CrMo needle bearings to resist severe shock loads, mechanical fatigue, and wear.
• Square Flange Connection: Features a standard 4-hole square flange configuration that facilitates secure bolting, easy assembly, and hassle-free maintenance inspection.
• Stable & Low-Noise Operation: Precision dynamic balancing and high-concentricity assembly ensure smooth rotational performance with low operating noise.
