Iimveliso zeemoto ezineebheringi, ngokwendima yezinto ezinxulumene nazo, zombini kwicala le-radial kunye ne-axial ziphantsi kwemida yokubeka indawo, isiphumo sayo esiya kuba nefuthe ekususweni kwebheringi, okubonakala ekususweni kokuqala kwebheringi kunye nomahluko phakathi kweimvume yokusebenza.
Isithuba esikwi-bearing ngumgama opheleleyo onokuhanjwa yi-radial okanye i-axial ring kwenye i-bearing ring. Ngokuphathelele isithuba se-bearing, kufuneka kwenziwe umahluko phakathi kwesithuba esingaphambi kokufakelwa kunye nesithuba emva kokufakelwa kunye nokufikelela kubushushu bayo bokusebenza. Isithuba esisebenzayo se-bearing sihlala sincinci kunesithuba sokuqala ngenxa yokunyamezelana okufanelekileyo kunye nokuphazamiseka okwahlukeneyo kunye namanqanaba ahlukeneyo okwandiswa kobushushu be-bearing rings kunye neendawo ezinxulumene nazo (umz. ii-motor shafts, i-end caps, njl.njl.), okubangela ukwanda okanye ukucinezelwa kwe-ring.
Imigaqo eqhelekileyo yolawulo kunye nobuchule: Indawo yokusebenza kweebheringi zebhola kufuneka ibe zero okanye ibe nomthwalo omncinci. Nangona kunjalo, kwi-roller esilinda, i-roller ejikelezayo kunye nezinye iibheringi, kufuneka kubekho indawo ethile yokusebenza eseleyo, nokuba incinci kakhulu.
Ngokubanzi phantsi kweemeko zokusebenza eziqhelekileyo, imvume yokusebenza efanelekileyo ingafumaneka ngokukhetha iibheringi ezinemvume eqhelekileyo yeqela. Nangona kunjalo, xaiimeko zokusebenza nezokufakelwazahlukile kwimeko eqhelekileyo, njengokuba iibheringi zeeringi zombini zifanelekile xa kukho ukuphazamiseka, okanye umahluko kubushushu beringi unefuthe elikhulu, ngoko ke indawo yokuvula kufuneka ikhethwe kuneqela eliqhelekileyo leebheringi ezinkulu okanye ezincinci.
Ngokuxhomekeke kwisicelo, iibheringi kufuneka zicwangciswe ngesithuba sokusebenza esihle okanye esibi. Kwiimeko ezininzi, isithuba sokusebenza kufuneka sibe sihle, oko kukuthi, ibheringi kufuneka isebenze ngesithuba esithile sokusala. Kwelinye icala, kukho izicelo ezininzi apho kufuneka isithuba sokusebenza esibi – oko kukuthi ukulayisha kwangaphambili –.
Ukulayisha kwangaphambili iibheringi kungasetyenziselwa ukwandisa ukuqina okanye ukuchaneka kokujikeleza kwee-bearing configurations. Imizekelo ibandakanya ii-spindle bearing kwizixhobo zoomatshini, ii-pinion bearing kwi-automotive driveshafts, ii-bearing kwiimoto ezincinci, okanye ii-bearing configurations zokunyakaza okuphindaphindayo. Kwezinye izicelo apho ii-bearing zingathwali mithwalo emincinci kakhulu, okanye zisebenza ngesantya esiphezulu, kufuneka kufakwe i-preload kwi-uqwalaselo lweebhereyithaKule meko, injongo yokulayisha kwangaphambili kukubonelela ngomthwalo omncinci kwibheri ukuthintela izinto eziqengqelekayo ukuba zingatyibiliki zize zonakalise ibheri.
Ukulayisha kwangaphambili kunokuba yi-radial okanye i-axial kuxhomekeke kuhlobo lwe-bearing. Umzekelo, ii-cylindrical roller bearings zinokufakwa kuphela kwicala le-radial ngenxa yoyilo lwazo, ngelixa ii-thrust ball bearings kunye nee-cylindrical roller thrust bearings zinokufakwa kuphela kwicala le-axial. Ii-single row angular contact ball bearings kunye nee-tapered roller bearings zihlala ziphantsi komthwalo we-axial kwaye zihlala zisetyenziswa kwizibini ezingasemva okanye ezijongene ubuso nobuso kunye nenye i-bearing yohlobo olufanayo. Ii-deep groove ball bearings zihlala zisetyenziswa ne-axial preload efanayo, ukuze kufezekiswe injongo yokulayisha kwangaphambili, kufuneka zisetyenziswe neqela elikhulu kunesiqhelo le-radial internal clearance, ukuze ibe ngathi ii-angular contact ball bearings zine-contact angle engaphezulu kwe-zero.
