Kwifom yokuqala ye-linear motion bearing, umqolo weentonga zokhuni zibekwe phantsi koluhlu lweepleyiti ze-skid. Iibheringi zentshukumo zanamhlanje zisebenzisa umgaqo ofanayo wokusebenza, ngaphandle kokuba ngamanye amaxesha iibhola zisetyenziswa endaweni yeerola. Eyona ndlela ilula yokujikeleza ngumkhono we-shaft, ophakathi kwevili kunye ne-asi. Olu yilo lwatshintshwa emva koko ziibheringi eziqengqelekayo, ezazisebenzisa iirola ezininzi zecylindrical ukuthatha indawo ye-bushing yokuqala, kwaye into nganye eqengqelekayo yayifana nevili elahlukileyo.
Umzekelo wangaphambili wokuthwala ibhola wafunyanwa kwinqanawa yamandulo yaseRoma eyakhiwe ngo-40 BC eLake Naimi, e-Italy: ibhola yeplanga yayisetyenziselwa ukuxhasa umphezulu wetafile ejikelezayo. Kuthiwa uLeonardo da Vinci wachaza ibhola ephethe malunga ne-1500. Phakathi kwezinto ezahlukeneyo ezingavuthwanga zeebheringi zebhola, inqaku elibaluleke kakhulu kukuba iibhola ziya kungqubana, zibangele ukukhuhlana okongeziweyo. Kodwa oku kunokuthintelwa ngokubeka iibhola kwiikheji ezincinci. Ngenkulungwane ye-17, uGalileo waqala wachaza ibhola ephethe "ibhola ye-cage". Ekupheleni kwenkulungwane ye-17, i-British C. wallow yayila yaza yavelisa iibheringi zebhola, ezafakelwa kwinqwelo yeposi ukuze zisetyenziswe ulingo, kwaye iBritish P Worth yafumana ilungelo elilodwa lomenzi wokuthwala ibhola. Isixhobo sokuqala sokuqengqeleka esinekheyiji sayilwa ngumenzi weewotshi uJohn Harrison ngowe-1760 ukwenza iwotshi yeH3. Ekupheleni kwenkulungwane ye-18, uHR hertz waseJamani wapapasha iphepha ngoxinzelelo lonxibelelwano lweebheringi zebhola. Ngokwesiseko seempumelelo zikaHertz, iJamani r. Stribeck kunye Sweden a Palmgren kunye nabanye baye benza inani elikhulu iimvavanyo, nto leyo eye yanegalelo kuphuhliso ithiyori uyilo kunye nokudinwa ubomi ukubala iibheringi rolling. Emva koko, uNP Petrov waseRashiya wasebenzisa umthetho kaNewton we-viscosity ukubala ukungqubana okukhoyo. Ilungelo lomenzi lokuqala kwitshaneli yebhola yafunyanwa nguPhilip Vaughn wasecamson ngo-1794.
Kwi-1883, uFriedrich Fisher ucebise ingcamango yokusebenzisa oomatshini abafanelekileyo bokuvelisa ukugaya iibhola zetsimbi ezinobungakanani obufanayo kunye nokujikeleza okuchanekileyo, okwabeka isiseko soshishino lokuthwala. U-O Reynolds wenze uhlalutyo lwemathematika lokufunyanwa kukaThor kunye ne-equation yeReynolds, eyabeka isiseko sethiyori ye-hydrodynamic lubrication.
