SA..E(S) Series Rod End Bearing Description

The SA..E (S)/SA..ES 2RS Series is a maintenance-required rod end bearing with external threads, specifically designed for high-load, regularly maintainable external linkage scenarios in equipment. It is equipped with left-hand or right-hand external threads and consists of a rod end body and a radial spherical plain bearing (GE..E (S)/GE..ES 2RS). The rod end body is made of medium carbon steel with environmentally friendly zinc plating. It adopts a steel/steel sliding pair; both the ball and outer ring are heat-treated bearing steel (HRC 54-60) with phosphating treatment. ES models are equipped with lubrication holes/grease nipples, and for specifications with d≥15, the optional 2RS double-seal structure effectively blocks dust and moisture from the external environment. The external threads allow direct and secure fastening with internal threaded holes on equipment frames. With its robust structure and strong load-bearing capacity, it is the preferred connector for high-load external linkages in heavy equipment.

Core Advantages

1. Steel/steel sliding pair for heavy load adaptation

2. Maintainable design suitable for outdoor regular maintenance

3. 2RS double-seal for upgraded outdoor protection

4. High-strength external thread fastening

5. Dual rust protection (phosphating + zinc plating)

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SA 20 ES 2RS.
For bearing bore diameter d ≥ 15, the -2RS sealed variant is also available, e.g., SI 20 ES 2RS.
Models marked with an asterisk (*) do not include a lubrication hole or grease nipple.
