Which outcome results from air ingestion causing vapor bubble implosion in hydraulic actuator rod bearings?

💡 Explanation

When air is ingested, cavitation bubbles form, and their subsequent implosion near the actuator rod bearings creates localized high-energy jets because of the rapid phase change, leading to material fatigue. Therefore, bearing pitting and accelerated wear occurs, rather than damping, thermal stress reduction, or improved lubrication which require boundary lubrication, heat sinking or smooth motions respectively.
