POSB
POSB rod ends are compact self-aligning spherical bushings that can support a large radial load and a bi-directional axial load at the same time. This type has superior anti-wear and anti-corrosion properties as well as high rigidity.
It consists of a spherical inner ring of which the spherical surface is chromium-plated after heat treatment and grinding, a body with zinc chromate treated outer surface, and an inserted bushing of a special copper alloy having superior run-in properties.
