Rod end bearings, incorporating a spherical plain bearing within the housing, are also known as "rod ends" or "spherical plain bearing rod ends." They are used in assemblies for connecting parts and facilitating relative motion.
Figure 1. Example of Rod End Bearing Use
Rod end bearings are essential in various sectors, including construction, industrial machinery, automotive, and aviation. They are pivotal in connecting and transmitting motion in parts that undergo rotational or oscillating movements. For instance, as shown in Figure 1, they are utilized in production lines to control the movement of workpieces.
The rod-end housing ends, featuring either "male" or "female" threads, are designed for secure attachment, allowing for the relative displacement of connected parts through a spherical sliding structure.
Rod end bearings facilitate smooth and flexible rotational motion, enabling connected parts to rotate and tilt freely, akin to human joints. They are capable of withstanding high loads, making them suitable for heavy-duty applications.
Figure 2. Structure of Rod End Bearing
As depicted in Figure 2, a rod end bearing comprises a "bush" (inner ring) and a "rod end housing" (outer part with threads for connection). These components allow for adjustable connections by threading the male rod into the female-threaded rod end housing.
Figure 3. Types of Rod Ends
Rod end bearings vary by shape, lubrication, and material, each tailored for specific applications and requirements.
Additionally, resin-made rod ends offer lightweight, maintenance-free options suitable for environments with contaminants.
Figure 4. Link Ball
Link balls, another variant, combine a threaded shaft with a bushing, often covered with a rubber boot to prevent ingress of water and dust, with lubricant sealed within for smooth operation.
