Are small turbine bearings usually lubricated by means of sight feed drop oilers?

1. True

2. False

The correct answer is: False

Small turbine bearings are not typically lubricated using sight feed drop oilers. Instead, they usually employ a more controlled lubrication method to ensure optimal performance and prevent overheating or wear. Small turbines often use a forced lubrication system where oil is circulated under pressure, allowing for a continuous supply of lubricant. This system can include oil pumps and lubrication lines that help provide a consistent and adequate flow of oil to the bearings, which is essential for maintaining their longevity and efficiency. In contrast, sight feed drop oilers are more commonly used in applications involving larger bearings or machinery where the visibility of oil flow is beneficial for monitoring purposes. They allow operators to visually confirm that lubrication is occurring correctly. For small turbine bearings, the precision and reliability of the lubrication system are more critical, leading to the preference for methods that provide more consistent and controlled lubrication.
