Pakutanga kwechimiro che "linear motion bearing", mutsara wematanda akaiswa pasi pemutsara wema "skid plates". Ma "linear motion bearing" emazuva ano anoshandisa musimboti mumwe chete wekushanda, kunze kwekuti dzimwe nguva mabhora anoshandiswa panzvimbo pema "rollers". "Rotary bearing" iri nyore i "shaft sleeve bearing", inova "bushing" yakasungirirwa pakati pevhiri ne "axle". Dhizaini iyi yakazotsiviwa nema "rolling bearing", ayo aishandisa ma "cylindrical rollers" akawanda kutsiva "bushing" yekutanga, uye chinhu chimwe nechimwe chinotenderera chakaita sevhiri rakasiyana.
Muenzaniso wekutanga webhora rinobata bhora wakawanikwa pangarava yekare yeRoma yakavakwa muna 40 BC muLake Naimi, Italy: bhora rinobata bhora rehuni raishandiswa kutsigira tafura inotenderera. Zvinonzi Leonardo da Vinci akatsanangura bhora rinobata bhora kunenge muna 1500. Pakati pezvinhu zvakasiyana-siyana zvebhora rinobata bhora, chinhu chakakosha ndechekuti mabhora anozobonderana, zvichikonzera kukweshana kwakawedzerwa. Asi izvi zvinogona kudzivirirwa nekuisa mabhora mumakeji madiki. Muzana remakore rechi17, Galileo akatanga kutsanangura bhora rinobata bhora re "cage ball". Pakupera kwezana remakore rechi17, British C. wallow yakagadzira uye yakagadzira mabheyaringi ebhora, ayo akaiswa pamotokari yetsamba kuti ishandiswe mukuyedza, uye British P Worth yakawana patent yebhora rinobata bhora. Bearing yekutanga inoshanda ine cage yakagadzirwa nemugadziri wewachi John Harrison muna 1760 kugadzira wachi yeH3. Pakupera kwezana remakore rechi18, HR hertz yeGermany yakaburitsa bepa pamusoro pekumanikidzwa kwekubata kwemabheyaringi ebhora. Zvichibva pakubudirira kwaHertz, r yeGermany. Stribeck neSweden's a Palmgren nevamwe vakaita bvunzo dzakawanda, idzo dzakabatsira mukuvandudzwa kwedzidziso yekugadzira uye kuverenga hupenyu hwekuneta kwema rolling bearings. Mushure mezvo, NP Petrov wekuRussia akashandisa mutemo waNewton we viscosity kuverenga kukweshana kwema bearing. Patent yekutanga pa ball channel yakawanikwa naPhilip Vaughn wecamson muna 1794.
Muna 1883, Friedrich Fisher akakurudzira pfungwa yekushandisa michina yekugadzira yakakodzera kukuya mabhora esimbi ane saizi yakaenzana uye kutenderera kwakarurama, izvo zvakava hwaro hweindasitiri yekutakura zvinhu. O Reynolds akaita ongororo yemasvomhu yekuwanikwa kwaThor uye akawana Reynolds equation, iyo yakaisa hwaro hwedzidziso ye hydrodynamic lubrication.
