Ma casters a mipando yaofesi, monga zigawo zazikulu za dongosolo lothandizira, amakhudza mwachindunji zomwe ogwiritsa ntchito akukumana nazo. Ma casters omwe amapezeka pamsika amagawidwa m'magulu awiri: mtundu wa flat plate ndi mtundu wopindika. Woyamba amamangiriridwa mwachindunji pansi pa mwendo wa mpando ndi zomangira, pomwe womaliza amalowetsedwa mkati mwa mwendo kudzera mu njira yolumikizira. Ma casters a nayiloni ndi oyenera pansi olimba, ma casters a rabara ndi abwino kwambiri pansi pamatabwa, ndipo ma casters a PU amaphatikiza kuchepetsa phokoso ndi kukana kuwonongeka. M'mimba mwake ma casters nthawi zambiri amakhala pakati pa masentimita 5 mpaka 7, ndi mainchesi akuluakulu omwe amafunika khama lochepa kukankhira koma amapereka kukhazikika kochepa. Ma casters opangidwa ndi mabuleki amabwera m'njira ziwiri zomangira: full lock ndi single-wheel lock. Full lock imakonza ma casters onse nthawi imodzi kudzera mu lever yapansi, yoyenera malo omwe amafunika malo okhazikika nthawi yayitali, pomwe single-wheel lock imawongolera kuzungulira kwa caster inayake, yomwe imapezeka kwambiri m'mipando yachipatala. Ma casters amitundu yamakampani amatha kunyamula mpaka makilogalamu 150, pomwe ma casters a mipando yaofesi wamba ali ndi mphamvu yolemera ya makilogalamu 80 mpaka 120. Kudzaza kwambiri kungayambitse ma bearing a mpira kusokonekera, zomwe zimapangitsa kuti pakhale phokoso losazolowereka. Mukayika ma casters, siyanitsani pakati pa ulusi wa kumanzere ndi wa kumanja, ndipo kuzungulira mozungulira nthawi zambiri kumakhala njira yochotsera. Kwa ma casters atsopano, kugwiritsa ntchito mafuta ochokera ku silicone poyamba kumachepetsa kukangana, pomwe mafuta ophikira ayenera kupewedwa kuti fumbi lisasonkhanitse mafuta. M'malo okhala ndi laminate pansi, ma casters ofewa a TPE ndi omwe amakondedwa, okhala ndi zinthu zoyesedwa kuti zikhale zolimba madigiri 60 mpaka 70 kuteteza pansi pamene zikuwonetsetsa kuti zikugwira ntchito bwino. Ma casters oletsa kusinthasintha amapezeka kwambiri m'malo ochitira labotale, omwe amafunika kukana pamwamba komwe kumayendetsedwa mkati mwa 10^6 mpaka 10^9.9Ω. Ma bearing a mpira ndi ma bearing a singano zimakhudza mwachindunji moyo wautumiki, pomwe oyambawo ndi oyenera kugwiritsidwa ntchito tsiku ndi tsiku muofesi ndipo omaliza ndi olimbana kwambiri ndi katundu wolemera. Yang'anani nthawi zonse ma grooves a bearing a mpira kuti muwone ngati akuwonongeka, ndipo musinthe mwachangu ngati pali kutsika koonekera kapena kukana kugwedezeka. Ma casters opangidwa ndi mawonekedwe apadera monga nyenyezi kapena zikhadabo makamaka amathandizira kukoka, abwino kwambiri m'malo otsetsereka koma ovuta kuyeretsa. Ngati caster ikumva kuchedwa, ichotseni ndikugwiritsa ntchito WD-40 rust remover kuti muyeretse ulusi wa tsitsi womwe wagwidwa mkati mwa bearing. Ma casters odekha samakhala chete konse, ndipo miyezo yapadziko lonse lapansi imafuna phokoso losakwana ma decibel 30. Mukamayesa, kankhirani mpando kutali ndi mamita 3. Ngati kukambirana kwabwinobwino sikukukhudzidwa, amaonedwa kuti ndi oyenerera. Ma casters ena apamwamba amakhala ndi kapangidwe ka mizere iwiri, komwe kamapereka mphamvu yonyamula katundu yoposa 30% poyerekeza ndi nyumba za mzere umodzi. Ngati mukukumana ndi mikwingwirima pansi, musasinthe ma casters nthawi yomweyo. Choyamba, yang'anani pamwamba pa gudumu kuti muwone ngati pali zinyalala monga mchenga kapena grit, ndikutsuka gudumu ndi burashi yofewa kuti muthetse vutoli. Mukagula, samalani makulidwe a caster bracket - mbale zachitsulo zopitilira 1.5mm zimakhala zolimba kwambiri. Ma casters otulutsa mwachangu amapereka kuyika kosavuta koma kosasunthika pang'ono poyerekeza ndi mitundu yokhazikika ndi zomangira, zomwe zimapangitsa kuti zikhale zoyenera mipando yamisonkhano yomwe imasunthidwa nthawi zambiri. Mitundu ina imakhala ndi kapangidwe ka masitepe, ndi kapangidwe ka maukonde komwe kamaletsa lint ndi ulusi kulowa mu ma bearing. Ma casters a mawilo ambiri nthawi zambiri amakhala ndi tread yokhala ndi mizere yozama komanso yosaya, zomwe zimathandiza kugwiritsa ntchito pamakapeti ndi pansi zolimba, ngakhale kuti kukana kwa ma gudumu kuli pafupifupi 15% kuposa ma casters apadera. Kukonza kumalimbikitsidwa kotala lililonse, kuphatikizapo kuyeretsa kwambiri ndi thonje loviikidwa mu mowa kuti mupukute axle. Kuti musunge nthawi yayitali, masulani ma casters ndikusunga mozondoka kuti mupewe kusintha kwa rabara kuchokera ku mphamvu ya mbali imodzi. Nthawi zonse sinthani ma casters m'magawo onse, chifukwa kusakaniza zakale ndi zatsopano kungayambitse kufalikira kosagwirizana kwa kupsinjika komanso kuwonongeka mwachangu. Ngati bracket ya caster yasokonekera, kugwiritsa ntchito mwamphamvu kungakanda pansi, zomwe zimapangitsa kuti pakhale kukonzedwa kwakanthawi ndi nyundo ya rabara kapena kusinthidwa ndi bracket yatsopano. Malo apadera amafunika kusankha molunjika: ma casters osagwira dzimbiri nthawi zambiri amapangidwa ndi chitsulo chosapanga dzimbiri cha 304, choyenera ku laboratories za mankhwala; ma casters otentha kwambiri amagwiritsa ntchito rabala yapadera ndipo amatha kugwira ntchito mosalekeza pa 80°C. Pomaliza, ogula ayenera kulangizidwa kuti ma casters osakwana 20 yuan nthawi zambiri amapangidwa ndi pulasitiki yobwezerezedwanso, yomwe imapereka mphamvu yonyamula katundu yosadalirika komanso yolimba, kotero malo aofesi ayenera kukhala patsogolo pazinthu zovomerezeka komanso zabwino.
