Hydrostatic or hydrodynamic ? Heavy duty truck or automotive ? https://www.mahle-aftermarket.com/m...s-and-literature/engine-bearings/eb-40-16.pdf The attached pdf has the "good stuff" from page 177. Note roundness, size, taper, surface finish, and even the direction of journal polishing can profoundly affect hydrodynamic bearing life. All is good, until it is not. Upvote 0 Downvote
