Sitimu yekufambisa i "bhiriji" pakati pesimba remabhurudhoza kubva painjini kuenda kumuchina wekufamba, uye mabearings anofanirwa kushingirira kusanganiswa kwe torque yakakwirira, simba, uye kutenderera kwepamusoro-kumhanya:
Kufambiswa: Tsigiro yemukati giya shaft inotsamira pane tapered roller mabearings (anogona kumirisana nezvose radial uye axial mitoro) uye cylindrical roller mabearings (akachinjirwa kune radial masimba pakumhanya kukuru) kuve nechokwadi chekufambisa kwesimba kwakagadzikana panguva yekuchinja kwegiya uye kuderedza zvikanganiso zvegiya meshing.
Dhiraivha shaft: Iyo shaft yedhiraivha inobatanidza giya bhokisi neekisero yekutyaira, uye mabhengi ayo anoitsigira anowanzo ari wega-anorongeka mabhengi, anogona kuchinjika padiki kutsauka kweshaft yedhiraivha zvichikonzerwa nekukanganisa kwekuisa kana mabumps, kudzivirira kutakura jamming.

Dhiraivha axle: Iwo mabearings ari mu main reducer uye mutsauko anoda kumira muhombe yekupedzisira transmission torque, uye kaviri mitsara tapered roller mabheji anowanzo shandiswa kuparadzira mitoro nekuwedzera simba rekubatana. Iyo yekufamba sisitimu yakanangana nepasi, uye mabearings anofanirwa kutsungirira huremu hwebulldozer pachayo (makumi ematani) uye pasi rekuita simba panguva yekutyaira uye kushanda:
Dhivha vhiri: Chinhu chikuru chinotyaira kushanda kwenjanji yacho, uye mabhengi ayo akakura-akaenzana mitsara miviri ine mabhengi anomonereka. Mhete yekunze ndeyekuvhiringidza inokodzera vhiri hub, uye mhete yemukati yakamisikidzwa pahafu shaft, iyo inogona kutsungirira radial mitoro inorema uye axial thrust, kuve nechokwadi kuti track haitsvedzeki kana kutsauka.
Kutsigira uye kutsigira mavhiri: Kutenderedza panjanji kutsigira muviri, mabearings anofanirwa kuve nekupfeka kwakasimba kuramba uye kuiswa chisimbiso. Seal roller bearings (zvakadai se cylindrical roller bearings ne rubber sealing rings) inowanzoshandiswa kudzivirira ivhu nejecha kuti zvipinde - kunyanya mumadhaka, mumigodhi nedzimwe nzvimbo, kuparara kwechisimbiso kunogona kukonzera kukurumidza kutakura kupfeka.

Gumbo rekutungamira: rinotungamira kwainoenda, uye mabhengi aro anowanzoita -kurongedza mabhengi, anogona kuchinjika kukona kunokonzerwa nekushanduka kwetension yetrack uye kuderedza chiitiko che track "gnawing".
Mabulldozer, maturusi ekusunungura, uye mamwe maturusi ekushanda anoburitsa zvakakomba masimba uye lateral masimba panguva yekushanda, uye mabearings anofanirwa kuve nekushanduka-shanduka uye kukanganisa kuramba:
Bulldozer blade hinge shaft: Pahinge shaft inobatanidza bulldozer blade uye silinda yemafuta inosimudza, majoint bearings (radial joint mabearings kana angular contact joint mabearings) anoshandiswa kubvumira blade kuti rizungunuke pane imwe kona panguva yekusimudza uye kurerekera, kudzivirira kushushikana kunokonzerwa nekubatana kwakasimba. Zvimwe zvinoshandisa self-kuzora majoint bearings (kusanganisira mafuta ekuzora) kuderedza mari dzekugadzirisa zvinokonzerwa nekuzora mafuta nguva zhinji.

Mudziyo wekusunungura: Iyo shaft yekubatanidza pakati pemazino ari kusunungura uye furemu inoda kushingirira kana yaiswa muvhu rakaoma kana dombo. Inonyanya kuve yakakura spherical inotsvedza inotakura kana yakavharwa roller fani, iyo inoyera kupfeka kuramba uye buffering kugona.
Iko kushandiswa kwemabulldozer bearings kunoda kuzadzisa zvitatu zvakakosha zvinodiwa:
Kutakura mutoro unorema: Yakagadzirwa nechimiro (roller bearing line contact) uye zvinhu (yakakwirira-simbi inotakura simba) kuti ienderane nemitoro yemakumi ematani;
Kushivirira kwezvakatipoteredza: Chimiro chakavharwa (labyrinth, double lip seal) uye kusakara-zvinhu zvisingachinjiki zvinodzivirira kukukurwa kweguruva, madhaka, mvura, uye tembiricha yepamusoro;
Dynamic adaptability: Mabhengi akakosha akadai sepakati uye majoini anobvumira kutenderera kushoma kana oscillation yezvikamu, kudzivirira kutadza kwekutanga kunokonzerwa nekuomarara kushushikana.
