Nk'ibice by'ingenzi, bloki za silinda za moteri n'imitwe ya silinda bigomba kwihanganira ubushyuhe bwinshi n'umuvuduko, bikagira icyizere cyo kuzifunga neza, kandi bigatanga uburyo bwo guhuza neza. Ibipimo byabyo bya tekiniki, harimo gupima ubukana n'ibizamini by'ubuziranenge, byose bisaba kugenzura neza hakoreshejwe ibikoresho by'ubuziranenge. Gupima ubukana bw'bloki za silinda n'imitwe bikoreshwa cyane cyane mu gusuzuma imiterere y'ibikoresho, no kwemeza ko byujuje ibisabwa mu gishushanyo.
Ibipimo by'ubukana bwa Rockwell bibereye mu gusuzuma ubukana bw'ubukana bw'ubuso bunini kandi burambuye nk'imirongo ya silinda (urugero: ubuso buhuza umutwe wa silinda, hasi ya silinda) n'impande z'umwobo wa crankshaft. Kugira ngo hagenzurwe ubuziranenge kuri interineti mu mirongo ikorwa, ibisabwa mu isuzuma ryihariye birashobora gutangwa. Ibipimo by'ubukana bwa Rockwell byikora bishobora guhuzwa n'umurongo ukorwa kugira ngo bigere ku bikorwa bidakozwe n'umuntu, bifite imikorere myiza kandi bihamye. Ubu buryo bwo gupima ni bwo bukoreshwa cyane mu gukora ibice by'imodoka kandi bwubahiriza amahame ya ISO 6508 na ASTM E18.
Ibipimo by'ubukana bwa Brinell birakoreshwa mu gupima ubukana bw'ibice by'ubugari bya silinda n'ibice bifite inkuta nini (urugero, ku mpande z'ibice by'ubugari bya silinda), kandi birakwiriye cyane mu gusuzuma ubwiza bw'ibice by'ubugari bya silinda by'icyuma gishongeshejwe n'ubushyuhe. Ni ngombwa kumenya ko gupima Brinell bisiga ibice binini, bityo bigomba kwirindwa ku bice byoroshye kwangirika nko ku buso bw'imbere bw'urukuta rwa silinda n'ubuso bukozwe neza.
Ibipimo by'ubukana bwa Vickers birakwiriye mu gupima ubukana bw'ibice by'inkuta ntoya za silindiri za aluminiyumu, ubuso bw'imbere bwa silindiri (kugira ngo budakwangiza ubuso bufunga), ndetse no gupima ubukana bw'ubukana bw'ibice n'amabati byasizwe ubushyuhe (urugero: imiterere ya nitride, imiterere yazimye) ku buso bwa silindiri. Ubu buryo bwo gupima bwujuje ibisabwa mu gupima ikirere n'imodoka zo mu rwego rwo hejuru, kandi bwubahiriza amahame ya ISO 6507 na ASTM E92.
Dukurikije utubumbe twa silinda n'imitwe ya silinda bikozwe mu bikoresho bitandukanye, ibipimo by'ubukana bikurikira bishobora kurebwa:
| Igice | Ibikoresho Bisanzwe | Ingano y'Ubukomere (HB/HV/HRC) | Intego y'isuzuma ry'ibanze |
| Ibyuma bya Silindari byakozwe mu cyuma | HT250/HT300 (Icyuma cy'imvi), Icyuma cya Graphite cya Vermicular | 180-240HB20-28HRC | Menya neza ko idashira cyangwa idahinduka |
| Agace ka silindiri ka aluminiyumu gakoreshwa mu gufunga | A356+T6, AlSi11Cu2Mg | 85-130 HB90-140 HV 15-25 HRC | Kuringaniza imbaraga n'ubushobozi bwo gukora imashini |
| Umutwe wa Silindari y'icyuma gikozwe mu cyuma | HT200/HT250, Icyuma gikozwe mu ibumba | 170-220 HB18-26 HRC | Ihangane n'ingaruka z'ubushyuhe bwinshi kandi urebe neza ko ubuso bufunga neza |
| Umutwe wa Silindari ya Aluminiyumu | A356+T7, AlSi12Cu1Mg1Ni | 75-110 HB80-120 HV 12-20 HRC | Kuringaniza imiterere yoroheje, uburyo ubushyuhe bushira n'imbaraga z'imiterere |
Ku bijyanye n'ibisabwa bitandukanye byo gupima moteri, Laizhou Laihua ishobora gutanga ibisubizo byihariye bishingiye ku bicuruzwa byihariye. Ibi birimo moderi zisanzwe, moderi zisanzwe z'ibikoresho byo gupima ubukana bya Rockwell, Brinell, na Vickers, ndetse n'igishushanyo mbonera cy'ibikoresho byihariye byagenewe ibicuruzwa - byose bigamije kunoza imikorere y'igerageza n'ubuziranenge bw'ibipimo.
