Kugerageza gusimbuza kunyerera no guhuza umubano bigaragara ko byashimishije no mumyaka yabanjirije amateka. Ishusho ikubita ni ugushushanya urukuta muri Egiputa. Ibuye rinini ririmo gutwarwa ahubwo byoroshye kubiti bizunguruka byashyizwe munsi yacyo. Uburyo ibyo binjije ibiti birimo gutwarwa kuruhande rwimbere uburyo uburyo bwo kuzenguruka ibintu bisanzwe mubikorwa byumurongo wibintu byuyu munsi.
Nubwo inyamanswa ya roza yibyatsi yitwa uko basubiye mu bihe bya kera, ntibakunze gukoresha mu ntangiriro z'imiti kugeza mu ntangiriro z'ibikoresho byo kwivuza bakoresheje imipira yabo myiza kandi yoroshye Byoroheje gusaba imashini zifatika.
Uburyo bwibanze bwo kuzungurukaIcyifuzo cy'umurongoyashinzwe mu 1946 iyo sosiyete y'Amerika yo muri Amerika, Thomson, Ubucuruzi Bushings Bushing (Ubwoko bwo kongera kuzenguruka). Ishingiro ryumurongo wuyu munsi (ibice bizunguruka hamwe na gari ya moteri birashobora kugaragara mumapaki yatanzwe mubufaransa mu 1932. Aya mapato, nubwo akubiyemo imirimo yose yibanze yabatumiye umurongo, biracyagomba gukomeza gutegereza imyaka ibarirwa muri za mirongo mbere yo gusabana ku isoko. Muri kiriya gihe, ibice byinshi byamashini bikoresha ibintu bizunguruka nka screw screw cyangwa imipira yumupira byafunguwe. Ubwoko butandukanye bwumupira (imiyoboro yumurongo) yazanwe ku isoko, harimo ubwoko bwuguruye. Hagati aho, ibintu byinshi byavumbuwe no kunonosora ubwoko busa bwakozwe kuriumurongo.
Twebwe,Pyg-Zojiang Ikoranabuhanga rya Pergin Technology Co, Ltd, ni uruganda rurebire rwibanda ku bushakashatsi no guteza imbere ibice by'urutonde rw'imirongo hamwe no guhuza umusaruro w'isi Ibikoresho byo gutunganya, kumenyekanisha ibikoresho mpuzamahanga byambere hamwe nikoranabuhanga rigezweho, Pyg ifite ubushobozi bwo gusa umusaruro wa ultra-ubwumvikane buke bwo kunyerera no kunyerera neza mm 0,003 mm.
