SWC Light-Duty Type Cardan Shaft/Universal Shaft/PTO Shaft/Drive Shaft

SWC Light-Duty Type Cardan Shaft with ISO Air Compressor Parts

Product Description

The SWC Light-Duty Type Cardan Shaft, also known as a Universal Shaft, PTO Shaft, or Drive Shaft, is an essential component in various mechanical applications. This versatile product is designed to transmit mechanical power in situations where direct coupling of driving and driven elements is not feasible. The robust construction and impeccable performance make it an indispensable part for machinery requiring smooth and reliable transmission of torque.

Why Choose Our SWC Light-Duty Cardan Shaft?

Careful Selection of Raw Materials

The cross is the core component of the cardan shaft, making the selection of raw materials particularly critical. For light and medium-duty sizes, we utilize 20CrMnTi special gear steel bars from SHAGANG GROUP. These bars are forged in a 2500-ton friction press to ensure the internal metallurgical structure meets stringent quality requirements. Each part undergoes rigorous geometric dimension inspections to align with the drawing specifications, followed by meticulous machining processes including milling, turning, quenching, and grinding.

Advanced Production Equipment

Our production facility is equipped with a four-axis linkage machining center, ensuring the symmetry of keyways and flange bolt holes are less than 0.02mm, significantly enhancing installation accuracy. The integrated 4-axis milling and drilling center ensure the symmetry and verticality of the cross shaft are under 0.02mm, thus increasing the journal cross assembly service life by 30%. This precision is crucial for the smooth operation of the cardan shaft at speeds exceeding 1000 rpm.

We utilize CNC machines for high-precision lathing of flange yokes and welded yokes. The use of CNC technology guarantees the accuracy of the flange connection and improves the surface finish. Our automatic welding machines, equipped with advanced welding mechanisms, ensure consistent and high-quality welds, reducing human error and enhancing overall welding effects.

Dynamic Balance Testing

High-speed cardan shafts require dynamic balance testing before leaving the factory. An unbalanced shaft can produce excessive centrifugal force at high speeds, reducing bearing life. The dynamic balance test eliminates uneven casting weight distribution and achieves the required balance quality, thus improving the universal shaft’s service life. Our facility includes high-precision dynamic balance test benches capable of reaching speeds up to 4000 rpm with a balance accuracy of G0.8.

Professional Transport Packaging

Our export cardan shafts are packed in robust plywood wooden boxes secured with iron sheets to prevent damage during long-distance transportation. These boxes meet international standards, ensuring safe arrival at any port worldwide.
