The fundamental specifications, including inner and outer diameters, width, threads, and other parameters, are discussed, as well as its wide applications in mechanical engineering, from mechanical arms to valves, and hydraulic cylinders, demonstrating its importance in precision connecting technology.
Inner Diameter (d): In the specifications of rod end bearings, the inner diameter refers to the bearing's ball inner ring.
Outer Diameter (D): Typically, this refers to the ball's outer ring of the rod end bearings.
Width (B): This refers to the side face of the entire ball of the rod end bearings.
Material: The balls in rod end bearings are usually made of bearing steel, although some specialized bearings for specific applications may use other materials.
Thread Size and Type: Rod end bearings typically feature a thread, allowing them to be easily secured into mechanical structures. The specifications will also include details about the thread size and type, such as metric or imperial.
Load Capacity (Static): This refers to the maximum load the bearing can withstand.
Self-lubricating or Requiring Lubrication: Some rod end bearings come pre-lubricated, allowing for smooth operation over a period of time, while others require periodic lubrication.
Applications: Rod end bearings find extensive use in equipment that requires connecting moving parts and allowing relative motion, such as in mechanical arms, valves, hydraulic cylinders, and more.
