In a Babbitt bearing, where are oil grooves typically located?

In a Babbitt bearing, the oil grooves are typically located in the unloaded section of the bearing. This design is purposeful because the primary function of the grooves is to facilitate the flow of oil and ensure adequate lubrication. By placing the grooves where the load is absent, they can effectively retain oil and allow it to distribute evenly across the bearing surface.

This placement helps prevent metal-to-metal contact in the loaded areas, where the pressure is greatest, thereby reducing wear and extending the life of the bearing. The oil trapped in these grooves provides a reservoir that supports lubrication even as the bearing operates under load. Additionally, this configuration avoids potential loss of oil from the loaded sections, ensuring that the bearing remains adequately lubricated throughout its operation.
