Rod end bearings, also known as spherical plain bearings or heim joints, are essential components in mechanical linkages, allowing for smooth motion and load transmission. These bearings consist of a spherical plain bearing with an eye-shaped head attached to a rod or shaft. This design enables articulation in multiple axes, accommodating angular misalignment and oscillating movements. Rod end bearings are commonly used in applications such as steering linkages, control arms, and hydraulic cylinders, where precise movement and load support are required.
