PHSB Inch Rod End Bearing is a documented maintenance required series for industrial linkage or pivot applications. Inch-series female thread; bronze-lined spherical surface. Use the main image for identification and the full product description for model-by-model dimensions and load data.
PHSB is the inch-series answer for a female-thread rod end that can be relubricated. The catalogue uses familiar UNF thread forms and covers PHSB3 through PHSB16. A bronze liner supports the spherical sliding surface, and the housing includes a lubrication path for periodic service.

For replacement work, record the existing bore, female thread, eye width and center-to-end dimensions before ordering. Inch rod ends that look similar can differ enough to upset linkage geometry. The catalogue drawing is therefore as important as the designation.
Treat the grease fitting as part of the installation envelope. It needs tool access and should not become the first point of contact at maximum articulation.
POSB supplies the male-thread inch format; PHS is the metric female-thread series; SI T/K is a metric maintenance-free option for designs that do not need periodic grease.
