What is the maximum thrust bearing temperature of an operating main engine or SSTG as indicated by RTE?

The maximum thrust bearing temperature of an operating main engine or ship service turbine generator (SSTG) is indicative of the operating conditions and the potential for equipment failure if temperatures exceed safe limits. A thrust bearing is a critical component that supports axial loads and helps maintain the proper alignment of machinery.

The range given in this question reflects commonly accepted thresholds found in operational guidelines. The correct answer indicates that 270°F is the maximum limit before any risk of overheating that could lead to damage in the thrust bearing. Maintaining temperatures at or below this threshold is essential for the longevity and safe operation of both the main engine and SSTG.

Operating at temperatures higher than this can result in lubrication breakdown, increased wear and tear on components, and even catastrophic failure if not monitored and managed properly. Alerting operators to keep an eye on the thrust bearing temperature ensures proper maintenance and operational safety measures are followed.

Understanding these operational parameters is crucial for machinist mates, as they directly impact the reliability and efficiency of machinery onboard. Knowing the correct maximum temperature helps in making necessary adjustments or interventions to prevent operational issues.
