🆕 Series Overview

The PHSB series is the inch-dimension female-thread rod end bearing with a bronze liner. The rod body has an internal UNF (Unified National Fine) thread and a lubrication hole or grease cup. Sliding contact surfaces are steel against bronze. 9 standard inch bore sizes from 3/16 inch to 1 inch.

PHSB bearings are dimensionally equivalent to US and UK inch-standard rod end bearings for equipment with imperial-dimension shafts and threaded connections. Suffix L for left-hand thread.

❓ Frequently Asked Questions

▶ What thread standard does the PHSB/POSB series use?

The PHSB and POSB series use Unified National Fine (UNF) inch threads. Thread specifications are listed alongside the bore diameter in the specification table. Ensure the mating clevis or rod end uses the same UNF thread class.

▶ Can metric and inch rod ends be used interchangeably?

No. The bore diameter and thread specifications are not interchangeable between metric (PHS/POS) and inch (PHSB/POSB) series even when nominal bore diameters appear similar. Always specify the correct series for your shaft and thread standard.

▶ What load units are used in the inch series specification table?

Cd (dynamic load rating) and Cs (static load rating) are given in pounds-force (lbf). Convert to kN by dividing by 224.8 if required.

▶ Is the bronze liner replaceable in the field?

No. The bronze bushing is press-fit into the outer race during manufacture and is not a field-replaceable part. When the liner is worn, replace the complete rod end bearing unit.

▶ What is the recommended re-lubrication interval for inch bronze series?

Re-lubricate every 200 hours of operation or more frequently in wet or contaminated environments. Use NLGI-2 EP grease or, for food-contact applications, NSF H1 approved grease.
