Rollerswaa tallaabada ugu xasaasisanhabka samaynta qabow-laabashada.Sidaa darteed, walxaha loo xushay rullaluistu waxay sidoo kale tahay arrin muhiim ah oo lagu qiimeeyo tayada amashiinka samaynta duub.Xulashada qalabka rollers-ka ee kala duwan waxay keeni doontaa farqi weyn xagga tayada astaanta iyo qiimaha wax soo saarka.Suuqa mashiinka samaynta duudduuban ee Shiinaha, walxaha rollers-ka waxaa sida caadiga ah loo qaybiyaa noocyada soo socda: 45 steel, 45 steel electroplated with Cr, GCr15, Cr12, Cr12MOV, iwm.
Warshado badan ayaa sidoo kale bedeli doona rollers si ay u tuuraan birta si ay u badbaadiyaan kharashka.Iibsadayaashu waxay u baahan yihiin inay si taxadar leh u kala saaraan markaad iibsanayso mishiinada.Sababo la xiriira waxyaabaha ka kooban biraha kala duwan ee walxaha kiimikada C, Cr, MO, V, iwm ee kor ku xusan dhowr nooc oo maaddooyinka, waxqabadka habka iyo qiimaha aad bay u kala duwan yihiin, sidaas darteed codsiga wax soo saarka sidoo kale waa ka duwan yahay.Gariiradaha caadiga ah ee leh wax-soo-saar ka yar 330Mpa iyo dhumucdiisuna ay ka yar tahay 1.5mm, sida xaashida kulul, xaashida qabow-duuban, PPGI, birta galvanized, 45 birta ama 45 birta chromed waxay buuxin kartaa shuruudaha.Si looga hortago in rollers-ku ay daxaloobaan oo ay u dheereeyaan nolosha adeegga rollers, Mashiinnada Linbay waxay ku dabaqaan nidaamka dhejinta chrome ee dhammaan 45 rollers birta ( dhumucdiisuna waxay tahay 0.05mm), iyo adkaanta daaweynta kulaylka ka dib waxay gaari kartaa 58-62HRC. waxay qiyaas ahaan la mid tahay adkaanta Cr12 iyo GCr15.Iyadoo dhimista kharashaadka, waxay helaysaa tayo wanaagsan isla waqti isku mid ah.Haddii aad rabto in aad soo saarto gariiradaha xoogga badan leh oo leh wax-soo-saar ka badan 350Mpa ama gariiradaha birta ah, Mashiinnada Linbay waxay dooran doonaan GCr15 ama Cr12 sida alaabada rolalka, kuwaas oo aad qaali u ah.Labadan walxood waxay leeyihiin caabbinta xirashada sare, xasilloonida kulaylka iyo xoogga cufan, waxqabadka guud ee heer sare ah.Waxaa ka mid ah, qaybta Cr12 waxay u dhigantaa Heerka Ameerikaanka D3.Marka laga soo tago in loo isticmaalo sida alaab duuban, Cr12 waxa kale oo loo isticmaalaa feedh, dhinta, iyo walxaha la galiyo.Qalabka ugu tayada sarreeya ee rollers waa Cr12Mov ama Japanese standard SKD11 ama American standard D2, taas oo aad qaali u ah marka la barbar dhigo kuwa kale, waxay leedahay caabbinta xirashada sare waxayna leedahay nolosha adeegga ugu dheer.Marka laga soo tago in loo isticmaalo sida shayga rullaluistuliga ah, Mashiinnada Linbay waxay inta badan u adeegsadaan walxahan jarista daabka.
Waxaas oo dhan ka sarreeya, waxaad dooran kartaa alaabta rullaluistemadka iyadoo loo eegayo shuruudaha astaantaada iyo miisaaniyadda maalgashiga.Mashiinnada Linbay waxay had iyo jeer ku siin doonaan xalka ugu fiican shuruudahaaga gaarka ah, si aad u soo iibsato mashiin samaynta duub oo aad ugu qanacsan.
