Heavy-Duty Power & High Efficiency: SWC-BH Standard Telescopic Cardan Drive Shaft

The SWC-BH Series Double Structure Cardan Drive Shaft (Standard Telescopic Welding Type) is a heavy-duty, high-capacity industrial power transmission solution engineered to withstand severe torsional stress and large angular misalignments. Specifically optimized as a highly reliable replacement component for heavy industrial applications and compatible machinery layouts like Hitachi equipment, this telescopic cardan shaft ensures continuous operation under demanding conditions. Its unique design features an integral fork head cross shaft universal coupling configuration, which eliminates structural weak points common in split-bolt yokes. This ensures safer, more dependable torque transfer across non-collinear power paths, shielding adjacent drive motors and gearboxes from catastrophic rotational stress.

As outlined in the data specification profile in cardan shaft, these industrial-grade shafts are manufactured from high-strength Alloy Steel bodies using a premium Steel (42CrMo, 20Cr Quenched) process. Designed to deliver superior mechanical torque within highly restricted rotating diameters, the SWC-BH series supports broad customization with a flange diameter range of 58–440mm, an allowable torque envelope of 1.25–1000 N·m, and a highly versatile 15 to 25-degree axis angle compensation capability.

Core Product Advantages / Unique Selling Points

• Superior Angular Compensation (15°–25°): Engineered with a wide axis deflection range, providing far greater installation flexibility than standard SWP layouts (which are limited to roughly 10 degrees).

• High-Strength Integral Fork Head Layout: The solid, one-piece integral fork yoke eliminates bolted-joint weaknesses, making heavy-duty transportation and torque delivery much more reliable.

• Maximum Load Capacity in Restrained Spaces: Compared to alternative flexible couplings of the same outer rotating diameter, it transmits significantly higher peak torque—perfect for compact machinery chassis.

• Exceptional Transmission Efficiency (98%–99.8%): Ultra-low friction design guarantees a high-power delivery track that minimizes energy loss, providing obvious cost-saving effects.

• Dynamic Telescopic Axial Compensation: Standard telescopic welding architecture allows the drive shaft length to expand and contract dynamically under operational vibration and load shifting.

• Ultra-Stable Operations & Low Noise: Precision-machined cross assemblies ensure smooth, quiet operation, simple disassembly, and minimal maintenance downtime.

• Secure Industrial Flange Connections: Employs a robust, slip-free flange linked shaft fixing method to ensure perfect concentricity with heavy output shafts.

• Direct Factory Customization Platforms: Manufactured in Guangdong, China, under strict international quality standards, providing comprehensive support for OEM, ODM, and OBM commercial blueprints.
