Kev xaiv cov khoom siv rau lub tes tsho bearing cuam tshuam rau lawv qhov kev ua tau zoo thiab kev pabcuam lub neej. Cov ntaub ntawv uas muaj xws li:
1. Hlau: Lub tes tsho steel bearing muaj lub zog siab thiab hardness, ua rau lawv haum rau siab -load thiab siab - daim ntawv thov ceev. Cov qib steel feem ntau suav nrog carbon steel, alloy steel, thiab stainless hlau. Stainless hlau bearing lub tes tsho kuj muaj kev tiv thaiv corrosion zoo, ua rau lawv haum rau qhov chaw ntub lossis corrosive.
2. Cam khwb cia hlau: Cam khwb cia hlau bearing lub tes tsho yog pheej yig thiab muaj kev hnav zoo thiab kev poob siab, ua rau lawv haum rau nruab nrab -load thiab qis- daim ntawv thov ceev. Txawm li cas los xij, cam khwb cia hlau muaj qhov tsis zoo toughness thiab nws yooj yim rau tawg nyob rau hauv kev cuam tshuam loads.
3. Copper Alloys: Copper alloy bearing tes tsho muaj cov thermal conductivity zoo thiab hnav tsis kam, ua rau lawv haum rau siab - kub lossis siab - kev sib txhuam. Cov tooj liab feem ntau suav nrog tooj liab thiab tooj dag, uas kuj muaj qee qhov nws tus kheej -lubricating zog.
4. Engineering Plastics: Hauv qee daim ntawv thov tshwj xeeb, xws li cov tshuab ua zaub mov lossis cov cuab yeej siv tshuaj, cov tes tsho ua los ntawm cov yas yas yuav tsim nyog. Engineering plastics muaj qhov zoo xws li lub teeb yuag, kev tiv thaiv corrosion, thiab tsis tshua muaj coefficient ntawm kev sib txhuam, tab sis lawv lub zog thiab kub tsis kam yog feem ntau qis dua rau cov khoom siv hlau.
