SWC Series Heavy-Duty Industrial Universal Joint Cardan Drive Shaft Assembly

Welded Telescopic & Fixed Flange Coupling with High-Torque Multi-Row Needle Bearing Cross Spider

The SWC Series Industrial Universal Joint Cardan Drive Shaft is a high-performance mechanical transmission assembly engineered for continuous heavy-duty operations, large torque demands, and dynamic shaft misalignments. Featuring heat-treated forged alloy hubs, high-frequency quenched spline shafts, and a robust cross-spider total assembly with multi-row needle bearings, the SWC series delivers precise torque transfer without rotational delay. Available in multiple telescopic and fixed configurations (BF, DH, CH, WH, WF, WD styles) with diverse flange mounting patterns (Square, Round, Face-Tooth, and Jaw-type), each unit undergoes strict dynamic balancing to guarantee minimal operational vibration and long service life.

Key Advantages & Features

• Multi-Row Needle Bearing Cross Spider Assembly: Cross journal assemblies utilize high-density, multi-row needle roller bearings with integrated grease lubrication nipples, ensuring high load capacity, superior wear resistance, and easy maintenance.
• Advanced Heat Treatment Process: Raw steel forgings undergo quenching and tempering, while the telescopic spline shaft undergoes full-body induction hardening for long-term fatigue resistance under severe shock loads.
• Extensive Structural Variants: Offered in 6 standardized drive configurations including standard telescopic flange (BF), short telescopic welded (DH), long telescopic welded (CH), non-telescopic welded (WH), non-telescopic flange (WF), and compact short non-telescopic (WD) types.
• Versatile Flange Connection Interfaces: Flange end connections can be customized into Square Flanges, Round Flanges, Hirth Face-Tooth Flanges, or Interlocking Jaw Flanges according to customer machinery specs.
• Precision Dynamic Balancing: Factory dynamic balancing eliminates high-speed rotational runout, minimizing machine vibration, bearing stress, and acoustic noise.
• Protective Anti-Corrosion Finish: Finished with heavy-duty anti-rust protective industrial paint (standard colors: industrial black or safety orange) for reliable operation in harsh environments.
