Hydraulic cylinder earrings rod ends bearing GK30DO

A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links, tie rods, or anywhere a precision articulating joint is required. 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 portion may be either male or female.
Introduction:

1. Bearings stretching rod or housing is made up of weldable steel.

2. The type GK..DO is made up of a spherical plain bearing of type GE..ES and a stretching rod with welding slope, there is a dowel pin at the end of the rod.

3. Spherical plain bearing is a special structure of the sliding bearing. Its structure is simpler than the Rolling by an inner and outer one within the sphere of spherical, can withstand a larger load, according to their different types and structures that can withstand the radial load, shaft to load or radial, axial joint load at the same time.
Material:

Ball: Chromium Steel GCr15, heat treated, surface phosphate-treated
Race: Chromium Steel GCr15, heat treated, surface phosphate-treated
