What is a Double Cardan Joint?

A double cardan joint, also known as a double universal joint, is a mechanical coupling used to transmit rotational motion between two shafts that are misaligned. In scenarios where a single universal joint (U-joint) can’t provide the necessary angle of rotation or compensation for misalignment, a double cardan joint offers a reliable solution.

The double cardan joint features a combination of two U-joints connected by a central cross-piece, effectively creating a longer and more flexible drive shaft system capable of handling higher operating angles, typically up to 90 degrees. This design ensures accurate positioning and provides increased flexibility while maintaining durability under higher operating conditions.

Benefits of Double Cardan Joints

1. Enhanced Flexibility for High Angles:
   Double cardan joints are ideal for situations where misalignment and high-angle motion are required. The design allows for smooth torque transmission even when there is significant angular deviation, making them suitable for many automotive, industrial, and agricultural applications.

2. Increased Load Capacity:
   Although double U joints can carry slightly lower loads compared to their single counterparts, they provide more flexibility under high angles. The reduced load capacity is due to additional bending moments that occur in the center section. These forces are transferred to the joints as added loads, which should be considered when selecting the appropriate coupling for the application.

3. Reliable Performance and Long Service Life:
   Double cardan joints offer the same level of reliability and longevity as single U-joints, thanks to their high-quality construction and robust design. They are engineered to perform consistently over time, even in demanding environments with high angles and rotational speeds.

4. Corrosion Resistance:
   For applications in harsh environments, lubricant-retaining boots are recommended. These boots help protect the joints and prevent the ingress of dust, moisture, and other contaminants, thus enhancing the lifespan and performance of the coupling in corrosive environments.
