FAQ

Question?
What is the difference between an SI 20 ES and an SA 20 ES rod end?

An SI 20 ES has a female (internal) thread on the housing, while an SA 20 ES has a male (external) thread. The 'I' in SI stands for 'Innen' (German for internal) and the 'A' in SA stands for 'Aussen' (German for external).

Question?
Does this SI 20 ES rod end require lubrication?

Yes. The 'ES' designation indicates a steel-on-steel sliding contact surface, which requires periodic lubrication to prevent wear and ensure smooth operation. Maintenance-free versions typically have a designation like 'C' or 'T' (e.g., SI 20 C) indicating a PTFE liner.

Question?
What are the typical load ratings for a standard SI 20 ES bearing?

While specific values depend on the manufacturer, a standard SI 20 ES rod end typically has a basic dynamic load rating of around 25-30 kN and a basic static load rating of around 50-60 kN. Always consult the manufacturer's datasheet for precise figures.
