Ibyiciro by'ingenzi by'imiyoboro y'itumanaho

Urunigi rwo kohereza amakuru rugizwe ahanini na: umunyururu w'icyuma kidashonga, ubwoko butatu bw'umunyururu, umunyururu wisiga, umunyururu w'impeta zifunga, umunyururu w'ibumba, umunyururu w'imashini zihinga, umunyururu ukomeye cyane, umunyururu wo ku ruhande, umunyururu w'izamuka ry'ibiciro, umunyururu wa moto, umunyururu w'ifatabuguzi ufunga, umunyururu w'ipine udafite aho uboheye, umunyururu w'igihe.

Umunyururu w'icyuma kidasembuye

Ibice byabyo bikozwe mu cyuma kitagira umugese, gikwiriye gukoreshwa mu nganda z'ibiribwa ndetse n'ibindi bishobora kwangirika byoroshye kubera imiti n'imiti, kandi gishobora no gukoreshwa mu bushyuhe buri hejuru n'ubushyuhe buke.

Ubwoko butatu bw'iminyururu

Iminyururu yose ikozwe mu byuma bya karuboni ishobora kuvurwa ku buso. Ubuso bw'ibice byayo butwikiriwe na nikeli, butwikiriwe na zinki cyangwa butwikiriwe na chrome. Bushobora gukoreshwa mu mvura yo hanze n'ibindi bihe, ariko ntibushobora gukumira ingese y'amazi akomeye ya shimi.

Urunigi rwo kwisiga

Ibice bikozwe mu bwoko bw'icyuma gikozwe mu cyuma gitwikiriwe n'amavuta yo kwisiga. Uru runigi rufite imiterere yo kudashira no kudashira, kudakomeza gusana (ntirushobora kubungabungwa), kandi rumara igihe kirekire. Rukoreshwa cyane mu bihe aho imbaraga ziba nyinshi, kudashira, kandi kudashira ntibishobora gukorwa kenshi, nko mu nganda zikora ibiribwa, gusiganwa ku magare, n'imashini zitwara amashanyarazi zidafite ubuziranenge bwinshi.

Umunyururu w'impeta upfundikiwe

Impeta za O-fishing zishyirwa hagati y’ibice by’imbere n’inyuma by’umunyururu w’umuzingo kugira ngo hirindwe ko ivumbi ryinjira kandi amavuta atava mu gipi. Umunyururu ushyirwamo amavuta mbere y’igihe. Kubera ko umunyururu ufite ibice byiza kandi ufite amavuta yizewe, ushobora gukoreshwa mu byuma bifunguye nka moto.

Umunyururu wa rubber

Ubu bwoko bw'umunyururu bushingiye ku munyururu wa A na B ufite icyuma gifata gifite ishusho ya U ku gice cyo hanze, kandi icyuma gifata (nk'icyuma gifata NR karemano, icyuma gifata SI, nibindi) gifata ku gice gifata kugira ngo cyongere ubushobozi bwo kwangirika no kugabanya urusaku. Kongera ubushobozi bwo guhangana n'ihungabana. Gikoreshwa mu gutwara abantu.
