1.Sucker ul centralizer waa nooc ka mid ah qalabka hoos u dhaca kaas oo si fiican u soo saara anti-abrasion, waxay si gaar ah ugu habboon tahay si fiican u soo saarista iyo ceelka jihada kaas oo ka sarreeya barta dhexe ee usha nuugista, oo ka hooseeya barta dhexe ee usha nuugista, jidhka usha leh naylon Centralizer si fiican ayuu u shaqeeyaa.
Usha nuugista waxay kor iyo hoos ugu dhaqaaqdaa tubbada, sababtuna tahay qallafsanaanta laastikada ah ee usha dhuuqida, usha iyo gidaarka tuubada saliidda way fududahay in la sameeyo khilaaf, tii waxay ka dhigtaa usha nuugista inay si fudud u jebiso, badhanka usha sucker wuxuu leeyahay dabacsanaan xoog leh, oo lagu taabtay tuubada gidaarku waxa uu yarayn karaa is jiid jiidka usha iyo tuubada,waxana uu kordhin karaa nolosha wax soo saarka unugga bamgaraynta. Centralizer-ku wuxuu ku xiran yahay usha nuugta, dhexroorka dibadda ee centralizer ayaa ka weyn isku xirka dhexroorka dibadda, si uu u sameeyo shaqada dhexe. Centralizer-ku wuxuu ka samaysan yahay walxo u adkaysta xidhashada xoogga sare, waxaana lagu taabtay tubbada si loo yareeyo naaxinta si loo gaaro ujeedada ka-hortagga abrasion.
