The ruoko uye the bushing, ndivo chinoita panzombe kuchitonhora rinopfungaira kupisa galvanization mutsetse, vari yakaiswa pamisoro uye maoko singi mupumburu uye pakudzikamisa mupumburu uye kushandiswa kushumira sezvo nemotokari mabheyaringi pakati mabhanzi izvi. Vanofanira kushivirira dambudziko kubva kumusoro tembiricha, ngura ne zingi wakaumbwa uye abrasion. Nokuda kwechikonzero ichi, zvetsika zvigadzirwa vane zvazvakashatira pfupi upenyu basa, murombo kugadzikana uye yakakwirira nzwisisika mutengo. With mazhinji zvinhu uye chinokosha mutoo, hatina akakurukura ruoko uye the bushing ngaatevedzane zvakawanda zvakanakira akaita kurwisa pamusoro dzakakwirira tembiricha, nemishonga pamusoro abrasion uye irambe ichishanda. Vanogona zvinobudirira kubatsira vatengi kuvandudza chigadzirwa unhu uye kuderedza nzwisisika cost, mutengi nawo zvinogutsa zvinoda kuti zvakasiyana kugadzirwa mitsetse.
