Inline Ball Joints & Swivels

Inline ball joints, known as damper control swivel ball joints, are used in conjunction with nuts for holding purposes, especially if the connecting linkage is threaded. Furthermore, DC inline ball joints are used for controlling the linkage system. Aetna Screw specializes in designing and manufacturing three types of ball joints - DC, DH, and DS damper control ball swivel joints.
