Our annual export value exceeds US$5–10 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. As an ISO9001-certified manufacturer, we present our 12-Month Warranty Universal Shaft Coupling Cardan Joint Assembly, a robust solution for power transmission applications. Each assembly comes with a Mill Test Report, ensuring material traceability and performance verification. This product combines durability, precision engineering, and a comprehensive warranty to meet the toughest demands of industrial, agricultural, and automotive systems.
Product Overview
The Universal Shaft Coupling, also known as a Cardan Joint Assembly, is designed to transmit torque between shafts that are not collinear, accommodating angular misalignment and axial movement. Our assembly is manufactured from high-strength alloy steel, heat-treated for enhanced fatigue resistance and longevity. It features precision-machined yokes and cross trunnions, equipped with needle bearings or plain bearings depending on application requirements. The complete unit is balanced and tested to ensure minimal vibration and optimal performance under high rotational speeds.

Frequently Asked Questions (FAQ)
-
Q: What does the Mill Test Report include?
A: It includes the chemical composition (C, Si, Mn, S, P, etc.) and mechanical properties (yield strength, tensile strength, elongation) of the raw material used in the yokes and cross shafts. -
Q: How long is the warranty, and what does it cover?
A: The product carries a 12-month warranty against manufacturing defects in material and workmanship. It does not cover damage due to misuse, improper installation, or normal wear. -
Q: Can I customize the length or flange pattern?
A: Yes, we offer customizable sizes. Please provide your required bore diameter, shaft length, and flange dimensions. Custom patterns require a drawing or sample. -
Q: What is the maximum torque capacity of your Cardan Joint Assembly?
A: Torque capacity depends on the size and material. For a typical 2-inch bore model, rated torque is approximately 500 Nm. Larger sizes can exceed 10,000 Nm. Contact us with your application details for a precise recommendation. -
Q: Is the assembly pre-lubricated?
A: Yes, most assemblies are pre-greased with high-temperature lithium grease. For regreasable models, we provide grease fittings. -
Q: Do you provide technical drawings or CAD files?
A: Yes, we can supply 2D and 3D drawings upon request to assist with integration. -
Q: What is the lead time for standard orders?
A: For standard sizes in stock, shipping can occur within 5–10 working days. Custom orders typically require 15–25 working days, depending on complexity. -
Q: Which ports do you ship from?
