Miniatur-Gleitgewindetriebe

Miniatur-Gleitgewindetriebe

Mit Durchmessern bis hinunter auf 2 mm und optionalen spielfreien Muttern erlauben Thomson Miniatur-Gleitgewindetriebe die Entwicklung miniaturisierter Lösungen, die bisher als unmöglich galten. Konfigurierbar, anpassbar und schlank: diese Gleitgewindetriebe reduzieren Größe und Gewicht von Geräten auf ein Minimum, ohne deren Präzision, Lebensdauer oder Funktion zu beschränken.
