API mafuta simbi mazino mabhiti IADC217 8.5 inches (215mm) yekuchera dombo
Product Description
Tricone bit use Journal bearing, hardfaced head bearing surface., cone inotakura inlaid with friction reduction alloy uyezve silverplated. Kuremerwa kwekutakura uye kubatwa kwekudzivirira kwekutakura kunovandudzwa zvikuru.
O-mhete chisimbiso chinogadzirwa nekunyanya kupfeka kuramba yakakwira yakazara buna ine yakawedzera chisimbiso chikamu uye yakanyatso kugadzirirwa yekuisa chisimbiso flange munzvimbo yekuisa chisimbiso yakawedzera kuvimbika kwechisimbiso. Iyo bit bearing inogona kuvharwa bhora
Kune simbi zino bhiti, zino repamusoro rakaomeswa nemhando nyowani yekupfeka resistan.
Material uye nekudaro yakawedzera hupenyu hwekushanda kweiyo yekucheka chimiro ichiri kuchengetedza yakakwirira ROP
----Kucheka Chimiro
Zino reSimbi: Yekutanga tungsten carbide yakaoma yakatarisana pamusoro, inosimudzira zvakanyanya kupfekedzwa kwezino.
Tungsten Carbide Insets: Yakasiyana mhando yemhando yepamusoro tungsten carbide inoisa inogona kurongedzerwa pamabhiti, nyanzvi uye.
Sarudzo yesainzi yekuisa sekuenderana neyakasiyana mashandisirwo uye kudhirowa maitiro kuti uwane yakakwira inoshanda kuchera
production.
