Ball sockets and bushings for cylinders

Ball sockets (also called ball cups) are the spherical-shaped components used as a bearing joint that is applied for connection between the hydraulic cylinder and the swing lever on one side and with the S-valve housing on the other side. From a structural point of view this connection has the advantage of ball socket joint so the socket itself has to be produced with high accuracy to the sphere on the piston rod. Ball sockets are made from bearing materials such as bronze alloys or composite plastics.

Bushings for cylinders are the support bearings for the positioning of the hydraulic cylinder in the hanger or “fork”. They also form a bearing system in the support brackets. In these cases the bushings for cylinders are working in pair with the S-valve housing or with support bracket.

The most common ball sockets and the bushings for cylinders are the following:
