The lubrication method that is not typically used for small turbine bearings is the grease pack. Small turbine bearings generally benefit from lubrication methods that provide a continuous flow of lubricant, minimizing wear and ensuring effective heat dissipation.

Grease packs are typically used in applications where a seal or enclosure is present, allowing the grease to remain in place for longer periods. However, in small turbine applications, the high rotational speeds and heat generated require a more fluid and dynamic lubricant to consistently reach all parts of the bearing. This is why methods such as sight feed drop oilers, forced oil systems, and manual oiling—where oil can be supplied directly and in a controlled manner—are preferred. These methods provide a stable lubrication environment, reduce friction, and enhance the overall efficiency and lifespan of the bearings in turbine systems.
