Tšepe e sebelisoang tlhahisong ea li-bearing tsa slewing e arotsoe haholo-holo ka mefuta e mene: 50Mn, 42CrMo, 20CrMnTi, le GCr15SiMn. Ho sekaseka ho hanyetsa ho tsofala ha meno a slewing, ho hlokahala ho kopanya litšobotsi tsa thepa, lits'ebetso tsa kalafo ea mocheso le maemo a ts'ebeliso. Kakaretso e latelang e ipapisitse le tlhaiso-leseling e amehang:

GCr15SiMn:Tšepe e nang le chromium e ngata e nang le khabone, e thatafetse ho 60-64HRC, e hanyetsa ho tsofala hantle, 'me e hanyetsa ho tsofala ho feta tšepe ea GCr15, e loketse ts'ebetso e boima. Khabone e ngata (1.05%) le chromium (1.5%) li etsa li-carbide tse thata, tse hanyetsang ho tsofala ka makhetlo a mane ho feta 20CrMnTi, e loketse ho hanyetsa ho tsofala le maemo a ts'ebetso a ho hanyetsa mokhathala. Masimo a ts'ebeliso ea eona a kenyelletsa mechini ea boenjiniere, li-shaft tsa phetisetso ea likoloi, jj.

20CrMnTi:Mofuta ona oa tšepe ke oa tšepe e nang le khabone e tlase, 'me bothata ba eona ba bokaholimo hangata bo ntlafatsoa ke ho sebelisoa ha carburizing le ho tima. E ka etsa lera la carburizing le thata haholo holim'a leino, ha e ntse e boloka matla le ho tiea hantle bohareng. Kamora kalafo, bothata ba bokaholimo bo ka fihla ho 58-64HRC, 'me bokaholimo bo boloka matla le ho tiea hantle, ka hona e na le khanyetso e ntle ea ho tsofala, haholo-holo e loketseng maemo a mosebetsi a boima, a lebelo le phahameng kapa a nang le tšusumetso, joalo ka li-bearing tsa slewing ho metallurgy, mechini ea merafo le masimo a mang.

42CrMo:Kaha ke tšepe ea alloy ea khabone e mahareng, hangata e fumana thepa e phahameng ea mechini ka ho e tima le ho e futhumatsa (ho tima le ho futhumatsa mocheso o phahameng), ka ho hanyetsa ho robeha ho itekanetseng, e loketse maemo a nang le meroalo e itekanetseng le ho se be le tšusumetso e matla. Leha ho le joalo, ha e bapisoa le tšepe ea khabone e tlase e phekoloang ka carburizing, ho hanyetsa ho robeha ha eona holim'a metsi ho ka ba tlaase. Botsitso ba ho futhumatsa le matla a mokhathala a 42CrMo le tsona li betere, ka bothata bo phahameng ba holim'a metsi, li loketse libaka tse phahameng tsa ho robeha. 42CrMo e loketse haholoanyane bakeng sa tlhahiso.li-bearing tsa ho slewing,ka matla a matle a ho hlahisa le ho tiea, e ka mamellang meroalo le litšusumetso tse phahameng hamolemo, 'me e loketse ts'ebetso ea nako e telele ea mechini ea kaho. Lisebelisoa tsena, kamora ho tima kapa ho futhumatsa meno, li ka netefatsa ts'ebetso e tsitsitseng ea meno nakong ea ts'ebeliso ea nako e telele, 'me hangata li sebelisoa e le li-bearing tsa ho slewing bakeng sa mechini e boima, li-crane tse kholo le lisebelisoa tse ling.

50Mn:Ena ke mofuta oa tšepe ea carbon manganese e sebelisoang haholo lits'ebetsong tse hlokang ho tiea ho hoholo le ho hanyetsa tšusumetso, empa ho hanyetsa ha eona ho tloaelehile 'me ho ka fihlela litlhoko tsa matla le ho hanyetsa ho tsofala ha meno a tloaelehileng a ho thiba. Tšepe ea manganese hangata e phekoloa ka mocheso (joalo ka ho tima) ho eketsa ho thatafala ha eona, empa bothata ba eona ba bokaholimo hangata bo tlase ho feta ba 20CrMnTi e tšoeroeng ka carburizing, 'me e kanna ea se sebetse ka botsitso joalo ka tšepe ea alloy libakeng tsa ho roala moroalo o boima. Bothata ba bokaholimo ba leino bo ka fihla ho 50-60HRC, e leng se etsang hore e lokele li-bearing tsa ho thiba tlas'a meroalo e tloaelehileng le maemo a mosebetsi.

Boemo ba ho hanyetsa ho roala: Ka kakaretso, GCr15SiMn e na le ho hanyetsa ho roala ho hoholo, ha 42CrMo le 20CrMnTi le tsona li na le ho hanyetsa ho roala ho hotle ka mor'a ho chesoa ka carburing le ho tima. Ho hanyetsa ho roala ho itšetlehile ka lera la carburing 'me ho ka etsahala hore e robale ka mor'a tšebeliso ea nako e telele; Ho hanyetsa ho roala ha 50Mn ho fokola haholo. Ha ho khethoa, maemo a itseng a ts'ebetso (joalo ka mojaro, lebelo, maqhubu a tšusumetso) le ntlafatso ea lits'ebetso tsa kalafo ea mocheso le tsona li lokela ho nahanoa. 

Bakeng sa likarolo tsa bohlokoa tse kang meno a ho bea slewing, haeba ho lokela ho nahanoa ka ho hanyetsa ho tsofala le ho hanyetsa ho ts'oaroa, 42CrMo e loketse haholoanyane, e na le matla a leka-lekaneng, ho tiea, le ho hanyetsa ho tsofala; Haeba o hloka ho leka-lekanya ho tiea ho hoholo le ho hanyetsa ho ts'oaroa, le tlas'a maemo a tloaelehileng a mosebetsi oa mojaro, 50Mn le eona ke khetho e ntle.

Litšebelisong tse sebetsang, khetho ea thepa ea meno a ho behela a slewing e hloka ho nahana ka botlalo ka lintlha tse kang maemo a ts'ebetso ea lisebelisoa, boholo ba mojaro, lebelo, tikoloho ea mosebetsi, le ho kopantsoe le theknoloji ea kalafo ea mocheso ho netefatsa hore ts'ebetso ea meno e fihlela litlhoko tsa moralo.
