Iibheringi zerola zeenaliti zokulungelelanisa ze-PNA12/28, ezineringi engaphakathi
Iibheringi zerola zeenaliti zokulungelelanisa zineringi engaphandle enomphezulu ongaphandle ojikelezileyo. Iiringi ezimbini zokuhlala zepolymer ezinomphezulu ongaphakathi ojikelezileyo zifakwe kwisingxobo sentsimbi esitsaliweyo kwaye zifakelwe phezu kweringi engaphandle. Olu yilo lwenza ukuba ibheringi ikwazi ukwamkela ukungalungelelani okungaguqukiyo kwe-shaft ngokumalunga nendlu. Kwiinkqubo apho i-shaft ingenakuqiniswa kwaye igaywe, kufuneka kusetyenziswe iibheringi ezineringi engaphakathi. Ukususwa kwe-axial okuvumelekileyo kwe-shaft ngokumalunga nendlu kunqunyelwe kwiibheringi ezineringi engaphakathi. Ukuba ukususwa kwe-axial okuvumelekileyo okubonelelwa yiringi engaphakathi esemgangathweni akwanelanga, kunokwenzeka ukusebenzisa iringi engaphakathi eyandisiweyo.
Iibheringi ezingenandandatho yangaphakathi ziyindlela entle kakhulu yokulungiselela iibheringi ezincinci, ukuba umngxuma unokuqina kwaye ucolwe.

Ukulungelelanisa ukungalungelelani okungaguqukiyo: Iibheringi zerola zeenaliti zokulungelelanisa ziyazilungelelanisa ngokwazo ukuya kuthi ga kwi-3° yokungalungelelani okungaguqukiyo.
Icandelo eliphantsi elinqamlezileyo: Kwizicelo apho kungekho ndawo ingako ifumanekayo, iibheringi zerola zeenaliti zokulungelelanisa zibonelela ngesisombululo esincinci.
Umthamo ophezulu wokuthwala: Ngenxa yenani elikhulu leeroli, iibheringi zeeroli zeenaliti zokulungelelanisa zinomthamo omkhulu wokuthwala umthwalo.
