Tlhaloso ea Sehlahisoa
Li-gear tsa rona tsa PEEK li etsoa ka theknoloji ea sejoale-joale e netefatsang boenjiniere bo nepahetseng le boleng bo tsitsitseng. Motsoako o ikhethang oa thepa ea PEEK le lits'ebetso tse tsoetseng pele tsa tlhahiso li fella ka li-gear tse nang le khanyetso e ntle ea ho tsofala, coefficient e tlase ea khohlano le karolelano e phahameng ea matla ho boima. Sena se etsa hore e be e loketseng lits'ebetso moo ho tšepahala le ho phela nako e telele li leng bohlokoa, joalo ka litsamaiso tsa phetisetso ea mojaro o moholo, mechini e nepahetseng le lisebelisoa tse boima.

Li-gear tsa PEEK li etselitsoe ho sebetsa hantle ho feta thepa ea li-gear tsa setso, ho kenyeletsoa le litšepe le li-plastiki tse ling, mabapi le ho hanyetsa ho tsofala, ho boloka boima ba 'mele le ts'ebetso ka kakaretso. Thepa ea eona e phahameng ea mechini e e lumella ho mamella mocheso o feteletseng, lik'hemik'hale tse senyang le meroalo e phahameng ntle le ho senyeha, e leng se etsang hore e be e loketseng lits'ebetso tsa bohlokoa moo ho hloleha ho sa mamelloeng. Li-gear tsa rona tsa PEEK li khona ho sebetsa libakeng tse thata, li fana ka ts'epo e sa bapisoeng le ho tšoarella, li fokotsa nako ea ho se sebetse ha bareki le litšenyehelo tsa tlhokomelo.
Ntle le ts'ebetso e ntle le ho tšoarella, li-gear tsa rona tsa PEEK li bonolo ho li kenya le ho li hlokomela. Thepa ea eona e bobebe le e sa senyeheng e etsa hore ho be bonolo ho e sebetsana le ho e kenya, e fokotsa litšenyehelo tsa basebetsi le nako.
