SA ES is the male-thread version of the serviceable spherical-plain-bearing rod end. A radial bearing insert sits in the eye while the shank screws into the mating linkage. The supplied catalogue runs from 6 to 80 mm bore, covering compact actuators through much larger pivot joints.

Typical Applications
Selection Guide
The first sizing conversation should include pin diameter, male thread, required center distance and whether a sealed insert is needed. Compare both dynamic and static ratings, then check how the load reverses in the actual machine.
Installation & Maintenance
Install with the joint centered through its normal working range. Grease access must not be blocked by the rod or adjacent plates.
