POSB Inch Rod End Bearing – Male Thread, Bronze Liner

POSB Inch Rod End Bearing is a documented maintenance required series for industrial linkage or pivot applications. External inch/UNF threaded shank; bronze-lined spherical contact. Use the main image for identification and the full product description for model-by-model dimensions and load data.

MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

POSB combines an inch-series male thread with a greasable bronze-lined rod-end eye. It is useful when the surrounding machine was designed around UNF hardware and changing to metric threads would create more work than the bearing replacement itself. The catalogue family spans POSB3 to POSB16.

Typical Applications

Imported machinery service

Inch-thread actuator linkages

Mechanical controls and pivot rods

Selection Guide

Thread pitch must be verified, not guessed from outside diameter. Measure the bore and compare the full drawing dimensions, especially center height and shank length, because those values set the linkage’s neutral position.

Installation & Maintenance

Relubricate on a schedule appropriate to contamination and movement rather than waiting for noise or looseness. Keep the grease nipple protected from impact.

FAQ

Bronze-lined spherical contact — what changes selection?
If the original joint uses a left-hand thread, note the hand explicitly together with the model.
Grease point for scheduled service — what should installers watch?
During installation, do not use the bearing eye as a lever to force mismatched parts into line; correct the linkage geometry first.
Mechanical controls and pivot rods — suitable duty?
Mechanical controls and pivot rods is a screening application for the POSB series; final size follows the model table and actual joint duty.
