In ring-oiled bearings, the diameter of the ring is typically designed to be twice that of the journal diameter. This design principle serves several purposes. First, a larger ring diameter allows for a more extensive oil reservoir, which facilitates better lubrication of the journal as it rotates. This is crucial for reducing friction and wear, enhancing the overall efficiency and lifespan of the bearing system.

Additionally, having a larger diameter helps distribute the load more effectively, reducing the stress on the bearing surfaces, which can improve their performance under heavy loads. By ensuring adequate oil flow and a larger surface area for load distribution, the design maintains optimal operating conditions.

This relationship of the ring diameter being twice that of the journal diameter is a standard in engineering practices concerning ring-oiled bearings, reflecting a balance between performance and durability in various applications.
