Product Description

In advanced power transmission systems where smooth, constant-velocity rotation must be maintained across significant angular misalignment, a standard single universal joint is often insufficient. The engineering solution is the double cardan u joint, a sophisticated assembly that effectively cancels out the velocity fluctuations inherent in simpler designs. Apexcoupling, a leading supplier of precision drive components, manufactures a robust and reliable double cardan u joint, engineered for demanding applications that require both high strength and smooth operational characteristics.

A double cardan u joint consists of two standard U-joints (universal joints) connected by a centering yoke or an intermediate shaft. This configuration allows the assembly to maintain a nearly constant velocity ratio between the input and output shafts, even at working angles up to 90 degrees. This is a critical advantage over single joints, as it dramatically reduces vibration, minimizes cyclic stress on connected bearings, and ensures smoother power delivery—essential for precision equipment and high-performance machinery.

Our double cardan u joint is constructed from premium quenched alloy steel, specifically 42CrMo or 20Cr. The quenching process significantly enhances the material’s surface hardness and core toughness, providing exceptional resistance to wear, fatigue, and impact under high cyclic loads. Torque is transmitted reliably through a secure keyway shaft fixing method, with an allowable torque range of 20.1 to 129 N.m. Designed for versatility, it features an inner hole diameter range of 10-20mm and an outer diameter of 20-36mm, suitable for compact yet powerful driveline integrations.

This component excels in applications where space, angle, and smoothness are critical. It is indispensable in high-performance radio-controlled (RC) models such as boats and cars, where precise control is paramount. In the agricultural sector, it provides the durable, flexible linkage needed for various implements. Its utility extends broadly to industrial environments, including manufacturing plants, construction equipment, and other machinery requiring a reliable, high-angle power transmission link. The assembly is finished with precision grinding for optimal fit and function.

Understanding that one size does not fit all, Apexcoupling offers comprehensive customization (OEM, ODM, OBM) for this double cardan u joint. We can tailor specifications including exact dimensions, torque capacity, special material treatments, and speed ratings (suitable up to 4000 RPM, with custom design for higher speeds) to meet your unique application challenges. Every joint is backed by a 1-year warranty and our commitment to quality manufacturing.

For engineers and designers seeking to eliminate driveline vibration and ensure efficient, smooth power transmission through challenging angles, the Apexcoupling double cardan u joint represents the optimal fusion of advanced mechanical design and rugged, high-grade alloy steel construction.
