Li-spindle Bearings tse Tloaelehileng ke Life?

 Li-bearing tsa spindleke pelo ea mechini e potolohang ka nepo, 'me ho utloisisa mefuta e tloaelehileng haholo ho thusa bareki ho khetha tharollo e nepahetseng bakeng sa ts'ebeliso ea bona. Li-bearing tse peli tse sebelisoang haholo tsa spindle kelibere tsa bolo tse hokahaneng le angularlelibere tsa rolara tse silindara. Li-bearing tsa bolo ea ho kopana tsa angular li amohela meroalo e kopaneng ea radial le axial ka bokhoni ba lebelo le phahameng, e leng se etsang hore e be e loketseng li-spindle tsa lisebelisoa tsa mochini, li-spindle tsa ho sila, le li-motor tse nepahetseng. Ka lehlakoreng le leng, li-bearing tsa cylindrical roller li ipabola ho jareng meroalo e boima ea radial 'me li fana ka ho tiea le kabo e ntle ea moroalo bakeng sa lits'ebetso moo mojaro oa axial o leng monyenyane kapa o sebetsoang ka thoko. Mefuta ka bobeli e fumaneha ka mefuta e fapaneng ea likhetho tsa ho kenya le ho tlosa ho lokisa ho tiea, boitšoaro ba mocheso, le ho nepahala ha ho sebetsa.

Qetello

Hobaneng o lokela ho kgetha di-spindle bearings tsa rona Di-spindle bearings tsa rona di kopanya thepa e tswetseng pele, tlhahiso e nepahetseng, le moralo o shebaneng le tshebediso ho fana ka bokgoni bo phahameng ba lebelo, bokgoni ba ho jara, le bophelo bo bolelele. Hore na o hloka di-angular contact bearings bakeng sa di-spindle tse lebelo le hodimo, di-cylindrical rollers bakeng sa meroalo e boima ya radial, kapa ditharollo tsa ceramic tse kopantsweng bakeng sa maemo a feteletseng, mefuta ya dihlahiswa tsa rona le tshehetso ya boenjiniere di netefatsa tshebetso e ntle le ho fokotsa ditjeo tsohle tsa beng. Kgetha di-biarings tsa rona ho fokotsa nako ya ho se sebetse, ho ntlafatsa boleng ba ho sebetsa, le ho eketsa dinako tsa tshebeletso.

Re fana ka puisano ea ts'ebeliso, tlhahlobo ea sampole, le khotheishene e potlakileng ho u thusa ho khetha bearing e phethahetseng ea spindle bakeng sa litlhoko tsa hau.
