The PHSA Series rod end bearings are the male-threaded variant of the PHS Series, featuring a steel-on-steel sliding surface with an external male thread for direct mounting into tapped holes. The robust construction supports high oscillating loads with reliable grease lubrication. Common uses include pneumatic cylinder rod ends, machine tool linkages, press mechanisms, and industrial valve actuators requiring compact, direct-threaded connections.
