Rod ends

Product Detail Information

Generally, rod end bearings consist of a spherical inner ring (that called a ball), a housing (that called a body) having a shank or extension with male or female feature and right - handed or left-handed thread and a bush. Spherical inner rings are manufactured from carbon chromium bearing steel which is heated, and precision ground, to minimize friction of contacting surfaces. Housings are made of medium carbon steel and bushes are made from Cu-Zn alloyed brass. 

Rod ends are mainly used in the construction of control rod linkages, under the status of tensile and compressive loads transmitted through the control rods. These types are self-aligning bearings designed to take both radial and thrust loads and to have a superior performance especially in rotational and oscillating motions. they are essential components to design machinery and improve their performances in various industrial fields.
