Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
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.
