Compact Power & Industrial Torsional Strength: SWC-BH Single Structure Universal Shaft Coupling

The SWC-BH Series Single Structure Universal Shaft Coupling delivers an ultra-robust, high-capacity mechanical link designed to smoothly transmit severe rotational torque across misaligned power paths. Engineered specifically for high-load industrial machinery like Steel Rolling Machines, heavy-duty plant drives, and crane systems, this single structure cardan joint eliminates the internal play and structural vulnerabilities common in multi-piece assemblies. By utilizing an advanced integral fork head cross shaft architecture, the yoke housing is forged as a single unified piece. This design eliminates weak points, reduces structural deflection under massive strain, and protects adjacent gearboxes and motors from catastrophic peak torque overloads.

As shown in the technical attribute profile in image_0e57bf.png, these heavy-duty industrial couplers are manufactured from premium Alloy Steel with high-strength steel yokes. Built to handle extreme operational conditions where rotational space is highly restricted, the SWC-BH single series features a scalable outer diameter Size (D) of 58–550mm, an expansive torque capacity spanning 0.18 to 710 KN.m, and an operational axis angle capability engineered up to 22 degrees.

Core Product Advantages / Unique Selling Points

• High-Strength Integral Fork Head Design: Built with a solid, one-piece yoke structure that removes split-bolt vulnerabilities, ensuring highly reliable power delivery and structural safety under heavy operational stress.

• Massive Torque Handling Threshold: Safely manages demanding continuous loads and high-impact torque spikes with a broad allowable rating from 0.18 up to 710 KN.m.

• Optimized Space-Saving Architecture: Delivers significantly greater torque than alternative multi-piece or flexible couplings of the same rotating diameter—highly advantageous for machinery with tight physical clearance constraints.

• Elite Energy Transmission Efficiency: Operates with an outstanding 98% to 99.8% transmission efficiency rating, minimizing internal friction losses and keeping operational energy costs low.

• Smooth, Quiet Operations: High-precision balancing of the internal cross shaft ensures stable power delivery, minimal running noise, and reduced vibration runout.

• Heavy Industrial Painted Protection: Covered with a premium protective painted surface treatment to shield the alloy steel core against rust, water spray, and aggressive industrial environments.

• Low Maintenance, High Service Life: Designed for straightforward assembly and disassembly, allowing quick maintenance turnarounds on the factory floor.

• Direct Factory Custom Sourcing: Expertly manufactured in Guangdong, China, with a flexible 1 Pcs MOQ and full support for direct OEM, ODM, and OBM product customizations.
