If the bearings of a piece of machinery are fed by a gravity feed lubricating oil system, what statement is true concerning the vertical arrangement of the lube oil tanks?

🔍 Key Concepts

• Gravity feed lubrication relies on oil flowing downward due to gravity, not being pumped under pressure. • Difference between a gravity tank (header tank supplying oil) and a reservoir/sump (where oil collects and returns). • The need for static head/height for oil to flow from the supply tank to the bearings.

💭 Think About

• For oil to flow by gravity to the bearings, where must the gravity tank be located in relation to the bearings? • Where does used lube oil normally drain after passing through the bearings in a typical machinery system? • Think of a simple household gravity-fed water system: where is the supply tank, and where does the used water end up?

✅ Before You Answer

• Verify which component must be higher than the bearings to allow gravity flow without a pump. • Verify which component is typically used as a collection point below the machinery after lubrication is complete. • Eliminate any option where gravity flow from the tank to the bearings would be impossible without extra pumping.
