Journal Bearings vs. Ball Bearings - What's the Difference?
Sep 27, 2021· Journal bearings require less radial space than rolling-element bearings but need more length axially. Journal bearings are more capable of managing shock and overload compared with ball and roller bearings. They are also less prone to fatigue. They can run quieter than rolling-element bearings, especially when the rolling-element bearings ...
