1, record of the rod end bearings

It is a mechanical articulating joint which is also known as a heim joint or rose joint. Such joints are used on the ends of control rods, steering links, tie rods, or everywhere a precision articulating joint is required. Generally, it consists of a spherically-shaped inner ring and a cylindrical bore for shaft mounting.Something About Rod End Bearings


2, unlikeness in dimensional specifications and features

Rod end bearings may be distinct due to distinct dimensional specifications and features. Load capacity and maximum angular misalignment are the most important specifications to consider. In most cases, bearing motion is symmetrical and the maximum angular misalignment is half of the total side-to-side range. Dimensional specifications comprise compose units, bore diameter, major diameter, bearing thickness, housing diameter, uncut length, and thread length.

 

English compose units comprise inches (in) and fractions of an inch. Metric compose units comprise millimeters (mm) and centimeters (cm). Bore diameter is the inner diameter (Id) of the bearing bore. Major diameter is the nominal diameter to the top of the threads. Bearing thickness is the distance through the bore.

 

Housing diameter is the exterior diameter (Od) of the bearing housing. uncut distance is the distance from the top of the housing to the end of the shank. In terms of extra features, some rod end bearings are self-lubricating or comprise a lubrication port.

 

3, distinct threads

A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a threaded shaft attached. The threaded measure may be either male or female. Rod end bearings attach to rods and shafts via a male stud with external threads or a female housing with internal threads. Right-handed threads tighten in a clockwise direction and are the most generally used type of thread. Left-handed threads tighten in a counterclockwise direction and must match the mating part.
