Dimensions and concentricity requirements for threaded clevis rod ends

- Sep 14, 2018 -

The threaded clevis rod ends is mainly used for the support portion where the concentricity is not high, and the working surface pressure is large, and the slow swinging and the turning motion are performed. The U-shaped rod end of the thread belongs to the sliding bearing, and is wear-resistant non-metallic material lubrication type, and also has oil passage lubrication type.

The dimensions and lubrication of the threaded clevis rod ends are different and can be found in the classification of plain bearings in the mechanical design manual. The narrow rod end joint bearing should refer to the so-called fisheye joint. The fisheye joints are distinguished according to the internal and external wires of the connection method: internal thread series SIG, external thread series SAG. The size of the inner and outer wires is the same as the inner diameter of the fisheye. For example, the fisheye joint with the joint is M12, and the inner diameter of the bearing is also D12. Widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries.

The threaded clevis rod ends should select a certain bearing type. When performing the operation, it is necessary to determine the required bearing size. The main factors that must be considered are the load, bearing load capacity and expected service life. The same is true when selecting rod end joint bearings. Spherical plain bearings and rod end joint bearings are available in a variety of designs and have different combinations of sliding contact surfaces. Each design and combination has unique properties that make it ideal for certain applications.
