A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links , tie rods , or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect 90-degree alignment between the ...
Heim was the original inventor of the Spherical Rod End Bearing that became known as the “Heim Joint” and “Heim Rod End”. In 1942, at the request of the US Army Air Force, Heim developed a four-piece spherical bearing for installation in the control system of fighter aircraft to improve maneuverability. [11]
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod animals. [2] A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are ...

The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other. Muscles contract to move the bone attached at the joint.
The volume of synovial fluid within the joint is insufficient to fill the expanding volume of the joint and gases dissolved in the synovial fluid (mostly carbon dioxide) are liberated and quickly fill the empty space, leading to the rapid formation of a bubble. [22] This process is known as cavitation. Cavitation in synovial joints results in a ...
Joints can also be classified based on their anatomy or on their biomechanical properties. According to the anatomic classification, joints are subdivided into simple and compound, depending on the number of bones involved, and into complex and combination joints: [19] Simple joint: two articulation surfaces (e.g. shoulder joint, hip joint)
