Ngokufanayo zakhiwe njengeebheringi zebhola, iibheringi zerola zinomgca wokudibanisa kunokuba zibe yindawo yokudibanisa, nto leyo ebenza babe namandla amakhulu kunye nokumelana okuphezulu kokutshaqeka. Iirola ngokwazo ziza ngeemilo ezahlukeneyo, oko kukuthi, i-cylindrical, i-spherical, i-tapered, kunye ne-needle. Iibheringi zerola ze-cylindrical zilawula kuphela imithwalo yokutyhala emincinci. Iibheringi zerola ze-spherical zinokuthwala ukungalungelelani kunye nokutyhala okungakumbi, kwaye, xa ziphindwe kabini, zityhala nakweyiphi na indlela. Iibheringi zerola ze-tapered zinokulawula imithwalo yokutyhala ebalulekileyo. Iibheringi zenaliti, uhlobo oluthile lweebheringi zerola ze-cylindrical, zinokuphatha imithwalo ephezulu ye-radial ngokobukhulu bazo, kwaye zinokwenziwa njengeebheringi zerola zerola zenaliti.

Ii-roller bearings ziyafumaneka njengoyilo olupheleleyo kwaye ii-needle bearings zihlala zilolu hlobo. Ii-needle bearings zisebenza kakuhle kakhulu xa kuhanjiswana, kodwa ukungqubana kuya kuba phezulu ngenxa yokuhlikihla ii-roller-counter-roller.

Xa usebenzisa ii-roller bearings ezisilinda kwi-shafts ezine-angular misalignment, kungcono ukusebenzisa ii-roller bearings ezimbini ezimfutshane ezibuyela umva kunokusebenzisa i-roller bear enye ende.

Ukukhetha iBhola okanye iRoller Bearing
Njengomthetho jikelele, ii-ball bearing zisetyenziswa ngesantya esiphezulu kunye nemithwalo elula kunee-roller bearing. Ii-roller bearing zisebenza ngcono xa zithwalwa ngoxinzelelo nangoxinzelelo.

Iibheringi zebhola zihlala zithengiswa njengeendibano kwaye zitshintshwa nje njengeeyunithi. Iibheringi zerola zihlala ziqhekeka kwaye i-roller carrier kunye neerola, okanye iiracing zangaphandle okanye zangaphakathi, zitshintshwa nganye nganye. Iimoto eziqhuba amavili angasemva zisebenzisa olu hlobo lwamavili angaphambili. Inzuzo yolu yilo kukuba iiracing zinokuncitshiswa zingene kwiishafts nakwizikhongozeli ukuze zenze iindibano ezisisigxina ngaphandle kokubeka emngciphekweni iirola ngokwazo.

Iibheringi zebhola ezinomqolo omnye zisemgangathweni kwaye zingasetyenziswa ngokutshintshana phakathi kwabavelisi. Iibheringi zerola azisemgangathweni kangako ngoko ke umntu ocacisayo kufuneka ajonge ikhathalogu yomenzi ukuze akhethe enye efanelekileyo kwisicelo.

Iibheringi ze-rolling-element zenziwe ngomlinganiselo othile we-internal clearance. Nakuphi na ukungalungelelani okushukumisa ibhola isuke kwindawo yayo kwaye kususe le clearance yangaphakathi akufuneki kube nefuthe elikhulu kubomi be-bearing. Iibheringi ze-roller zinovelwano ngakumbi kwi-angular misalignment. Umzekelo, i-ball bearing esebenza ngesantya esiphakathi kwaye ingena kakuhle ingasebenza ngempumelelo nge-angular misalignment ephezulu njenge-0.002 ukuya kwi-0.004 in./in. phakathi kwe-bearing kunye ne-shaft. I-roller bearing esilinda, xa kuthelekiswa, inokuba nengxaki ukuba ukungalungelelani kudlule kwi-0.001 in./in. Abavelisi ngokubanzi baya kubonelela ngeentlobo ezamkelekileyo ze-angular misalignment kwiibheringi zabo ngabanye.
