Chitoliro Chobowola Cholemera Cholemera
Integral heavyweight kubowola chitoliro ndi kusintha zone pakati kubowola kolala ndi kubowola chitoliro.Iwo sangakhoze kokha kuchepetsa nkhawa-mapangidwe kugwirizana kwa kubowola kolala ndi kubowola chitoliro, komanso kuchepetsa kuvala pa OD.
Chitoliro chobowola cholemetsa chophatikizika chimapangidwa kuchokera ku chidutswa chimodzi cha AISI 4145H cholimba, chotenthedwa kwathunthu, zinthu zonse zakuthupi zimagwirizana ndi API spec7 kope laposachedwa.
HWDP's wear resistance resistance banding ndiyokhazikika pamalumikizidwe olumikizira zida komanso kukhumudwa kwapakati.Mitundu yamagulu olimba imaphatikizapo Arnco 100XT ndi100XT.Ulusi uliwonse ndi phosphated, copperized kapena ozizira ntchito.Malumikizidwe onse ali ndi zida zotchingira ulusi wachitsulo.Mipikisano yonse imapangidwa ndi CNC lathes -Mapewa awiri ndi ulusi wapadera.
