A rod end bearing consists of a spherical plain bearing and an eye-shaped body with an integral shank. The spherical plain bearing, typically made of stainless steel or other high-performance materials, is a self-aligning bearing that allows angular misalignment between the shank and the bore. The bearing is often composed of an inner ring with a spherical convex outside diameter and an outer ring with a matching concave inside diameter.
The shank of the rod end is threaded, which facilitates easy mounting and adjustment. The opposite end of the shank has a hole or a ball socket, where a bolt or another linkage element can be attached, connecting the rod end to the desired mechanical component.
There are various types of rod end bearings available, each designed to suit specific applications and load capacities.
This model features a male-threaded shank and is used when the rod end needs to be threaded into a component.

POS is a product composed of a steel inner ring and a bronze outer ring spherical sliding bearing. Its characteristics include excellent self-lubrication performance and wear resistance, and it can rotate and oscillate at any angle. It also has features such as shock resistance, corrosion resistance, and abrasion resistance, making it a high-value product.

With a female-threaded bore, this model is suitable for applications where a bolt or a stud is inserted into the rod end.
PHS is a type of bearing with a unique structure. Its inner and outer rings are made of high-carbon chromium bearing steel, which undergoes processes such as quenching, grinding, and coating. The PHS bearing consists of a steel ball as the sphere, which contacts a housing with a spherical bore, providing support and guidance.
