Isenzakalo sokuklwebha kububanzi obungaphandle bezinto ezigingqayo: amadents ayisiyingi endaweni yokuxhumana yezinto ezigoqekayo.Ngokuvamile kunemikhondo ehambisanayo yokuzungeza kuma-roller, bheka uMfanekiso 70 no-71, futhi into ethi “i-hairball” ivamise ukuba khona kumabhola, bheka uMdwebo 72. Akufanele kudidaniswe nokulandela onqenqemeni (bona isigaba 3.3.2.6).Unqenqema lwethrekhi olwakhiwe unqenqema olugijima lubushelelezi ngenxa yokuguqulwa kwepulasitiki, kuyilapho ukuklwebheka kunemiphetho ebukhali.Izinhlayiya eziqinile zivame ukushumeka emaphaketheni ekheji, zibangele umunyu, bheka uMdwebo 73. Imbangela: Isithambisi esingcolile;izinhlayiya eziqinile ezishumekwe emaphaketheni ekheji zisebenza njengezinhlayiya ezilumayo esondo lokugaya Ikhambi: - liqinisekisa izimo zokufaka ezihlanzekile - lithuthukisa ukuvala - lihlunga i-lubricant.

Isenzakalo samamaki ashelelayo: izinto ezigoqayo ziyashelela, ikakhulukazi amarola amakhulu nasindayo, njengamabheringi e-INA agcwalisayo.Slip roughens imigwaqo yomjaho noma izinto eziginqikayo.Impahla ivamise ukwakha ngezimpawu zokudonsa.Imvamisa ayisakazwanga ngokulinganayo endaweni kodwa emabala, bheka uMdwebo 74 no-75. Imigodi emincane ivame ukutholakala, bheka isigaba 3.3.2.1 “Ukukhathala ngenxa yokungagcotshisi kahle”.Izimbangela: - Uma umthwalo uphansi kakhulu futhi ukugcotshwa kukubi, izinto eziginqikayo ziyashibilika emijahweni.Ngezinye izikhathi ngenxa yokuthi indawo yokuthwala incane kakhulu, ama-roller anciphisa ngokushesha emaphaketheni ekheji endaweni engalayishiwe, bese esheshisa kakhulu lapho engena endaweni yokuthwala.- Izinguquko ezisheshayo ngesivinini.Izinyathelo zokulungisa: - Sebenzisa ama-bearings anomthamo ophansi womthwalo - Layisha ngaphambili ama-bearings, isb. ngeziphethu - Yehlisa ukudlala okudlalayo - Qinisekisa ukuthi umthwalo owanele noma ungenalutho - Thuthukisa ukuthambisa

Isenzo sokuklwebheka: Kumabhere angama-cylindrical roller ahlukanisekayo noma ama-roller ama-tapered, ama-elementi aginqikayo kanye nemigwaqo yomjaho kushoda okokusebenza okuhambisana ne-eksisi nokulingana kusuka kuma-elementi aginqikayo.Kwesinye isikhathi kuba khona amasethi amaningana amamaki esiqondisweni se-circumferential.Lo mkhondo uvame ukutholakala kuphela endaweni eyindilinga cishe engu-B/d kunesiyingi sonke, bheka uMfanekiso 76. Imbangela: Ukungaboni ngaso linye nokuhlikihlana lapho ufaka i-ferrule eyodwa kanye ne-ferrule enezinto ezigingqayo.Kuyingozi kakhulu uma uhambisa izingxenye zesisindo esikhulu (lapho i-shaft ewugqinsi enendandatho yangaphakathi eveza indandatho kanye nomhlangano wesici esigoqayo iphushwa iringi yangaphandle esivele ifakiwe ezindlini ezithwalayo).Ikhambi: - Sebenzisa amathuluzi okufaka afanelekile - Gwema ukungahambi kahle - Uma kungenzeka, jika kancane lapho ufaka izinto.
