Cov kabmob yob yog cov kabmob uas siv cov ntsiab lus dov rau kev txhawb nqa thauj khoom thiab txo kev sib txhuam. Nyob rau hauv sib piv rau pob bearings, dov bearings muaj barrel-puab yob cov ntsiab es tsis muaj rooj tog. Lawv muaj peev xwm nqa cov nra hnyav dua uas zoo sib xws pob pob kabmob, tab sis tsis tuaj yeem lis raws li kev kub ceev li cov pob txha kub. Cov Menyuam Bearings muaj cov nplhaib sab hauv thiab lub nplhaib sab nraud uas lub tsev cov kabmob thiab cov kabmob pob. Tawb, kuj tseem hu ua tawb lossis separators, tswj qhov kev sib tw ntawm cov chais thiab ua kom cov kabmob ua ke.
Muaj ntau hom cov kabmob dov, txhua tus nrog cov qauv sib txawv rau cov ntawv thov sib txawv; cylindrical, kheej kheej, tapered thiab rab koob yob yog plaub lub ntsiab ntawm cov menyuam cov kabmob with radial thauj khoom ntawm kev kub ceev; Lawv kuj tau yoog raws li nrawm nrawm. Spherical Menyuam Bearings muaj ob lub nplhaib rau sab hauv kev sib tw ua ke los lis ntau yam hluav taws xob thiab cov teeb meem sib dhos, thiab cov menyuam yaus sib koom ua ib tog kheej kheej ntiv nplhaib ntiv nplhaib. Nrog ob kab ntawm spherical Barrel rollers, kheej kheej kheej cov kabmob bearings tuaj yeem tiv thaiv loj radial thauj khoom thiab qee yam axial thauj khoom hauv ob qho lus qhia.
Lawv yog tus kheej ua raws li kev daws teeb meem los daws teeb meem kev tsis ua haujlwm Tapered Cov Menyuam Bearings muab cov lus tsa suab tseeb thiab kev sib txhuam tsawg, zoo tagnrho rau kev txhawb nqa cov khoom hnyav. Koob bearings siv tau senderer cylindrical rollers los txhawb radial loads. Muaj kev sib deev nyias muaj nyias dua lwm cov menyuam cov kabmob.
