Heavy-Duty Dynamic Drive: SWC Cross-Type Universal Joint Cardan Shaft

The SWC Series Cross-Type Universal Joint Cardan Shaft  provides high-efficiency power transmission across misaligned components in heavy industrial machinery. Engineered to serve as a high-strength flange drive shaft connector, this product line supports both BH Type (Standard Layout) and WF Type (Flanged Layout) configurations. Whether specified with a fixed length or integrated with a sliding telescopic spline for axial compensation, these cardan assemblies are heavily utilized in steel rolling mills, paper mills, lifting cranes, and large-scale industrial fluid pumps where mechanical alignment changes constantly.

Built from premium round bar forged steel and high-grade cold-drawn seamless steel tubes, the components undergo deep thermal engineering. The raw blanks are refined via quenching and tempering , while the internal spline shafts are subjected to an intensive overall induction hardening process . This ensures maximum torque transfer up to a nominal 1000 N·m and supports continuous high-velocity performance up to 1800 RPM.

Core Product Advantages

• Premium Forged Steel & Seamless Tube Frame: Constructed from high-strength forged steel and cold-drawn seamless steel tubing, delivering superior material density, structural toughness, and a long service life that limits physical wear under heavy reversing loads.

• Multi-Row Needle Bearing Cross Spider: The central cross assembly uses high-precision multi-row needle roller bearings, expanding the load support area, minimizing frictional drag, and providing excellent mechanical transmission efficiency.

• Convenient Lubrication Access: The cross spider features an integrated oil injection port (注油孔) that guides grease directly into the needle bearing cavities for fast, easy maintenance and reliable protection against heat wear.

• Overall Spline Hardening & Tempering: Thermal processing refines the steel blanks through tempering, while the central telescopic spline section undergoes an overall quenching process to ensure high wear resistance under heavy sliding cycles.

• Strict 1500 RPM Dynamic Balancing: To eliminate high-velocity vibrations and protect system bearings, every long-shaft cardan assembly undergoes strict factory dynamic balancing tested up to 1500 RPM.

• Protective Anti-Rust Surface Finish: Covered in an industrial-grade anti-corrosion spray paint finish to seal the underlying steel from moisture, splash water, and harsh plant environments.

• Direct Manufacturer Customization & Quick Sizing: Backed by Apexcoupling’s advanced production plant, we offer quick model selection, technical layout print provisioning, and full support for custom lengths, specialized flanges, non-standard outer diameters, and unique bore designs.
