High-Torque Mechanical Endurance: SWC Telescopic Universal Joint Cardan Shaft

The SWC Series Heavy-Duty Telescopic Universal Joint Cardan Shaft is designed to deliver reliable power transmission in demanding industrial applications. Engineered to connect misaligned driving and driven components across long distances, this telescopic cardan shaft accommodates high variations in axial distance while continuously transferring torque. It is an excellent match for heavy industrial settings like steel rolling machines, paper mills, large crushing equipment, and heavy-duty conveyor systems.

Constructed from premium 42CrMo and 20Cr Alloy Steel, the critical load-bearing cross pins and structural yokes undergo an intensive thermal quenching process. This advanced metallurgy allows the cardan coupling to manage an operating angle up to 45 degrees, withstand dynamic torque profiles ranging from 1.25 N·m to 1000 N·m, and operate reliably at rotation speeds up to 4,000 RPM.

Core Product Advantages

• High-Strength Quenched Alloy Metallurgy: The body and cross assembly are forged from premium 42CrMo and 20Cr alloy steels subjected to an advanced quenching process, maximizing tensile strength, core toughness, and fatigue life.

• Smooth Telescopic Axial Compensation: Built with an integrated spline telescopic section that automatically expands and contracts during operation, protecting your bearings from axial stress when distances shift.

• Wide 45° Operating Angle: The specialized cross-yoke geometry allows for smooth, continuous power transmission even at large angular misalignments up to 45 degrees.

• Robust 1.25 to 1000 N·m Torque Envelope: Built to handle high starting torque, heavy shock loads, and sudden rotational reversals without suffering material deformation or joint slip.

• Secure Flange-Linked Connection: Uses standard high-tensile flange bolt circles to simplify installation, ensure positive physical locking, and maintain exact concentric alignment with machinery hubs.

• Optimized for Steel Rolling Mill Demands: Engineered specifically to meet the high vibrations, heavy continuous reverse loading, and harsh environments typical of steel rolling mills.

• Full OEM/ODM Direct Factory Customization: Backed by Apexcoupling’s advanced production plant, we can customize flange diameters (ranging from 100mm to 620mm), closed/extended lengths, and dynamic balancing requirements based on your technical drawings.
