UNR-Gewinde ASME B1.1-2003

UNR-Gewinde (Unified Thread Series with External Thread Controlled Root Radius) sind eine spezielle Form des amerikanischen Einheitsgewindes, das mit einer konstanten Steigung und präzise definierten Maßangaben für den Grundradius des Außengewindes ausgestattet ist.

Diese Gewindeart wurde entwickelt, um den Anforderungen in der Maschinenbauindustrie und anderen präzisen Anwendungen gerecht zu werden, bei denen die Belastbarkeit und Langlebigkeit der Gewindeverbindungen entscheidend sind. Der kontrollierte Grundradius verbessert die Festigkeit und reduziert die Gefahr von Ermüdungserscheinungen.

Das UNR-Gewinde ist besonders nützlich in Anwendungen, die eine hohe Festigkeit und Widerstandsfähigkeit gegen Abrieb und Korrosion erfordern. Der Flankenwinkel beträgt 60°.
