Hi, I would like to establish a advancing/learning way to learn and understand machine elements. Today I tried to search for hydrodynamic radial sliding bearings on search engines but I have find only two results. Is something wrong for it? it should have another names. Source:https://www.google.com.tr/#q="hydrodynamic+radial+sliding+bearing"&tbm=bks Source:http://en.wikipedia.org/wiki/Mixed/dual_cycle I know from seilinger combustion cycle that the name seilinger is especially for German. In English, the common name or concept for that cycle is dual cycle or limited pressure cycle or mixed cycle, seilinger is rarely used. There must be something like seilinger for my search on those bearings. Have a nice day.
