The bearing shaft and/or the bearing bushing are configured to be rotatable. The bearing arrangement includes a primary bearing surface disposed on the bearing bushing, arranged to face a secondary bearing surface disposed on the bearing shaft. The primary and/or secondary bearing surfaces includes first regions having a first fluid slip characteristic, and second regions having a second fluid slip characteristic substantially different to that of the first fluid slip characteristic. The second and first regions are in a same plane of a cross-section of the primary and/or secondary bearing surfaces, and are disposed in an interleaved pattern over the primary and/or secondary bearing surfaces."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hydrodynamic bearings","description":"A self-acting, sealed hydrodynamic bearing includes a bearing shaft; a bearing bushing arranged to seal a length of the bearing shaft; a lubricant provided in the sealed length of the hydrodynamic bea","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9771978","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
