Ya ƙunshi zoben hanyar tsere mai siffar wanki (zoben shaft, zoben wurin zama) da abin nadi na silinda da abubuwan keji. The cylindrical roller rungumi dabi'ar convex surface sarrafa, don haka da matsa lamba tsakanin abin nadi da kuma tseren surface ne a ko'ina rarraba, kuma zai iya jure daya-hanyar axial load. Yana da babban ƙarfin nauyin axial da ƙarfi mai ƙarfi.
Babban amfani: na'urorin hako mai, ƙarfe da injinan ƙarfe.
12 Tuƙa abin nadi na allura
Rarraba bearings sun ƙunshi zoben tsere, rollers allura da taron keji, kuma ana iya haɗe su ba bisa ka'ida ba tare da siraran zoben tsere ko yanke-yanke mai kauri mai kauri. Abubuwan da ba za a iya raba su ba su ne ƙaƙƙarfan bearings waɗanda suka haɗa da daidaitattun zoben titin tsere, rollers allura da taron keji. Suna iya jure wa nauyin axial unidirectional. Irin wannan nau'in yana ɗaukar sarari kaɗan kuma yana dacewa da ƙayyadaddun ƙirar injina. Yawancin su kawai ana amfani da abin nadi na allura da taron keji, kuma ana amfani da farfajiyar hawa na shaft da gidaje azaman filin tsere.
Babban amfani: na'urorin watsawa don motoci, masu noma, kayan aikin injin, da sauransu.
13 Tuƙa maɗaurin abin nadi
Irin wannan nau'in na'ura an sanye shi da nadi mai siffa mai siffar mazugi (babban ƙarshen yana da siffar zobe). Ana jagorantar rollers daidai da haƙarƙarin zoben hanyar tsere (zoben shaft, zoben wurin zama). Zane-zane yana tabbatar da cewa shimfidar layin tsere na zoben shaft da zoben wurin zama da kuma saman mirgina na rollers Ƙarfin kowane wuri mai ma'ana yana tsaka-tsaki a wani wuri a kan tsakiyar layin ɗaukar hoto. Ƙaƙƙarfan hanyoyi guda ɗaya na iya ɗaukar nauyin axial na hanya guda ɗaya, kuma nau'i-nau'i biyu na iya ɗaukar nauyin axial na hanyoyi biyu.
Babban manufar:

Biyu kwatance: mirgina niƙa mirgine wuyansa.
14 Saka ƙwallo mai siffar zobe tare da wurin zama
An hada ball mai zina da zobe mai zaman kansa wanda ke da ƙwallon ƙafa a cikin bangarorin a garesu da kuma simintin karfe (ko farantin karfe) mai ɗaukar hoto. Tsarin ciki na ƙwallon ƙwallon ƙafa na waje yana daidai da na ƙwallo mai zurfi mai zurfi, amma zoben ciki na wannan ɗaukar hoto ya fi na waje zobe. Zoben na waje yana da farfajiyar waje mai ma'ana, wanda za'a iya daidaita shi ta atomatik tare da madaidaicin saman wurin zama.
Babban amfani: hakar ma'adinai, karafa, noma, masana'antar sinadarai, yadi, bugu da rini, injinan jigilar kayayyaki, da sauransu.
