La lubrification du joint torique<\/h1>\n

Lubrifiants \u00e0 usage g\u00e9n\u00e9ral pour les \u00e9lastom\u00e8res de joint torique<\/h3>\n

Dans toutes les applications dynamiques, une lubrification ad\u00e9quate et une bonne dissipation de la chaleur sont essentielles \u00e0 la dur\u00e9e de l’\u00e9tanch\u00e9it\u00e9 et la performance. Dans des applications pneumatiques, lubrification suppl\u00e9mentaire devrait \u00eatre fournie. Les lubrifiants doivent \u00eatre choisis sur la base de la mati\u00e8re dont l’O-anneau est fait et le type de service auquel il sera soumis. (voir tableau). Dans d’autres cas, le lubrifiant peut \u00eatre moul\u00e9 dans le O-Ring, ou en t\u00e9flon ou autres rev\u00eatements peuvent \u00eatre appliqu\u00e9s \u00e0 la surface.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
