UNIVERSAL JOINTS

Universal Joints, in their simplest form, consist of two shaft yokes at right angles to each other and a four-point cross that connects the yokes. The cross sits inside the bearing cap assemblies, which are pressed into the yoke eyes.

The modern Universal Joints have become much more complex than their simple ancestors described above.

In general, industrial applications must operate continuously with high torque loads. Industrial applications demand maximum strength and life of all components, including Universal Joints.

The most significant feature is the ability of the Universal Joints to operate at high misalignment angles.

Another key feature of Universal Joints is the design of the bearing and seal, which resists lubrication loss and contamination. This makes Universal Joints suitable for applications where harsh atmospheric conditions would prohibit the use of other couplings.

The Universal Joints can be used either as a single joint or in pairs. However, the use of the Universal Joints as a single joint, only accommodates angular misalignment.

Since nearly every application requires the coupling to accommodate offset misalignment as well as angular, the Universal Joints should be used in pairs. Using the Universal Joint in pairs also corrects for any non-uniform angular velocity that can be caused by a single joint
