Makina otumizira ndi "mlatho" pakati pa mphamvu ya bulldozer kuchokera ku injini kupita ku makina oyenda, ndipo ma fani akuyenera kupirira kusakanikirana kwa torque, kugunda, ndi kuzungulira{0}}kwamphamvu:
Kutumiza: Thandizo la shaft yamkati yamagetsi imadalira mayendedwe a tapered roller (omwe amatha kupirira ma radial ndi axial) ndi ma cylindrical roller bearings (omwe amasinthidwa ndi mphamvu zama radial pa liwiro lalikulu) kuwonetsetsa kufalikira kwamphamvu pakusuntha kwa zida ndikuchepetsa zolakwika za meshing.
Shaft ya Drive: Shaft yomwe imalumikiza gearbox ndi axle yoyendetsera, ndipo ma fani ake nthawi zambiri amakhala okha-odziyendetsa okha, omwe amatha kusintha kuti atembenuke pang'ono chifukwa cha zolakwika kapena mabampu, kupeŵa kukwera.

Drive axle: Ma fani mu chochepetsera chachikulu ndi masiyanidwe amafunikira kupirira torque yayikulu yomaliza, ndipo mizere iwiri yodzigudubuza nthawi zambiri imagwiritsidwa ntchito kubalalitsa katundu powonjezera mphamvu yolumikizana. Dongosolo loyenda limalumikizana mwachindunji ndi nthaka, ndipo mayendedwe amayenera kupirira kulemera kwa bulldozer palokha (makumi a matani) ndi mphamvu yakuyankha pansi pakuyendetsa ndikugwira ntchito:
Mawotchi oyendetsa: Chigawo chapakati chomwe chimayendetsa kayendedwe ka njanjiyo, ndipo mayendedwe ake amakhala akulu kwambiri-ndi mizere iwiri yozungulira yozungulira. Mphete yakunja ndi kusokoneza komwe kumayenderana ndi gudumu, ndipo mphete yamkati imakhazikika pa shaft theka, yomwe imatha kupirira zolemetsa zolemetsa komanso kuthamanga kwa axial, kuwonetsetsa kuti njanjiyo siterera kapena kupatuka.
Mawilo othandizira ndi othandizira: Kugudubuza m'mphepete mwa njanji kuti kuthandizira thupi, mayendedwe amayenera kukhala ndi kukana kolimba komanso kusindikiza. Miyendo yosindikizidwa yosindikizidwa (monga ma cylindrical roller bearings okhala ndi mphete zosindikizira mphira) nthawi zambiri amagwiritsidwa ntchito kuteteza nthaka ndi mchenga kuti zisalowe - makamaka m'matope, migodi ndi malo ena, kulephera kwa chisindikizo kungayambitse kuvala mofulumira.

Gudumu lolondolera: limatsogolera komwe njanji ikupita, ndipo ma mayendedwe ake nthawi zambiri amakhala okha-amakhala odzigudubuza okha, omwe amatha kusintha kuti agwirizane ndi kusintha kwa njanji ndikuchepetsa "kutama" kwa njanji.
Ma bulldozers, zida zomangira, ndi zida zina zogwirira ntchito zipangitsa kuti pakhale zovuta komanso mphamvu zakutsogolo panthawi yogwira ntchito, ndipo ma fani amayenera kukhala osinthika komanso kukana kukhudzidwa:
Bulldozer blade hinge shaft: Pa hinge shaft yolumikiza tsamba la bulldozer ndi silinda yamafuta, ma bere olowa (radial joint bearings kapena angular contact joint bearings) amagwiritsidwa ntchito kulola kuti tsambalo ligwedezeke pokweza ndi kupendekeka, kupewa kupsinjika komwe kumachitika chifukwa cha kulumikizana kolimba. Nthawi zina amagwiritsa ntchito ma berelo odzipaka okha (kuphatikiza mafuta olimba) kuti achepetse ndalama zolipirira chifukwa chopaka mafuta pafupipafupi.

Chipangizo chomamasula: Mtsinje wolumikiza pakati pa mano omasuka ndi chimango uyenera kupirira kukhudzidwa ukalowetsedwa mu dothi lolimba kapena mwala. Nthawi zambiri chimakhala chozungulira chachikulu chozungulira kapena chodzigudubuza chosindikizidwa, chomwe chimatchinjiriza kukana komanso kutsekeka.
Kugwiritsa ntchito ma bearings a bulldozer kumafunika kukwaniritsa zofunikira zitatu:
Kunyamula katundu wolemera: Wopangidwa ndi dongosolo (zodzigudubuza zonyamula chingwe kukhudzana) ndi zakuthupi (zapamwamba-zitsulo zonyamula mphamvu) kuti zigwirizane ndi katundu wa matani makumi;
Kulekerera zachilengedwe: Zomangira zomata (labyrinth, double lip seal) ndi kuvala-zinthu zosagwira ntchito zimalimbana ndi kukokoloka kwa fumbi, matope, madzi, ndi kutentha kwakukulu;
Kusinthasintha kwamphamvu: Ma bere apadera monga malo olumikizirana ndi olumikizira amalola kupotoza pang'ono kapena kusuntha kwa zigawo, kupewa kulephera koyambirira komwe kumachitika chifukwa cha kupsinjika kolimba.
