Cov kabmob yog ib feem tseem ceeb ntawm cov tshuab thiab khoom siv niaj hnub no. Nws lub luag haujlwm tseem ceeb yog txhawb nqa lub cev sib hloov lub cev, txo kev sib txhuam coefficient thaum nws txav mus los, thiab xyuas kom nws qhov kev sib hloov raug (raug). Daim ntawv txheej thaum ntxov ntawm cov kab lus tsa suab yog tso cov kab ntoo nyob hauv qab kab ntawm daim phiaj nplua. Cov kab tawm suab niaj hnub siv cov txheej txheem ua haujlwm zoo ib yam, tab sis qee zaum siv pob tsis siv cov menyuam. Cov kabmob uas yooj yim tshaj plaws yog cov kabmob bushing, uas tsuas yog ib lub hav txwv yeem nyob nruab nrab ntawm lub log thiab lub qag. Qhov kev tsim qauv no tau hloov pauv tom qab los ntawm cov kabmob dov, uas hloov qhov qub hav txwv yeem nrog ntau lub tog raj kheej. Txhua lub caij dov tau zoo li lub log sib cais.
Ib qho piv txwv ntawm kev nqa pob thaum ntxov tau tshawb pom ntawm lub nkoj Roman thaum ub tau tsim hauv 40 BC hauv Naimi Lake, Ltalis: lub pob ntoo tau siv los txhawb nqa lub rooj tig. Nws tau hais tias Leonardo da Vinci ib zaug piav qhia lub pob ib puag ncig 1500. Ntawm ntau yam yam tsis paub tab ntawm cov kabmob pob, muaj lub ntsiab lus tseem ceeb heev uas kev sib tsoo ntawm cov pob yuav ua rau muaj kev sib txhuam ntxiv. Tab sis qhov tshwm sim no tuaj yeem tiv thaiv tau los ntawm kev muab cov pob rau hauv lub tawb me me los ntawm ib qho. Xyoo pua 17th, Galileo tau piav qhia ntxov tshaj plaws ntawm" tawb pob" pob kabmob Qhov kawg ntawm lub xyoo pua kaum xya, British C. Wallo tau tsim thiab tsim cov kabmob pob, thiab teeb tsa lawv ntawm cov tsheb thauj khoom rau kev sim, thiab Askiv P. Tsim nyog tau txais daim ntawv pov thawj rau cov kabmob pob. Thawj dov cov kabmob nrog lub tawb kom muab tso rau hauv kev siv tau tsim los ntawm tus saib xyuas John Harrison hauv 1760 los ua H3 chronograph. Qhov kawg ntawm lub xyoo pua kaum yim, German HR Hertz tau tshaj tawm ib daim ntawv hais txog kev sib cuag ntawm kev sib tw ntawm pob bearings. Raws li Hertz' kev ua tiav, R. Stribeck hauv Tebchaws Yelemees, A. Palmgren hauv Sweden thiab lwm tus tau ua ntau qhov kev sim, uas tau pab txhawb rau kev txhim kho ntawm cov kabmob uas tsim qauv kev xav thiab lub neej kev qaug zog . Tom qab ntawd, Russia's NP Petrov tau thov Newton txoj cai ntawm viscosity los xam cov kabmob sib txhuam. Thawj daim ntawv patent ntawm lub pob zeb tau txais los ntawm Philip Vaughan ntawm Carmarthen hauv 1794.
Xyoo 1883, Friedrich Fisher tau thov kom siv cov tshuab tsim khoom los zom cov pob hlau ntawm qhov loj me thiab qhov sib npaug raug, uas tau tso lub hauv paus rau kev lag luam kabmob. British O. Reynolds tau ua qhov kev ntsuas ua lej ntawm Thor qhov kev tshawb pom thiab muab los ntawm Reynolds equation, yog li tso lub hauv paus rau hydrodynamic lubrication theory.
