POSB Series Rod End Barings

This model POSB is a highly rigid rod end that is basically the same as the female-screw type model PHSB, but has a male thread on the holder end. The POSB has the same structure as POS series, while the POSB is in inch size, and the POS is in metric size. Both types are compact self-aligning spherical bushings that can support a large radial load and a bi-directional axial load at the same time.
