Ihe mkpuchi seramiiki zirconia:

A na-eji ihe seramiiki zirconia (ZrO2) na-ebu ihe mgbanaka na ihe na-atụgharị, a na-ejikarị polytetrafluoroethylene (PTFE) eme ihe maka ndị na-ejide ya, na eriri iko na-agbanye naịlọn 66 (RPA66-25), plastik engineering pụrụ iche (PEEK, PI) ma ọ bụ igwe anaghị agba nchara (AISI). SUS316) na brass (Cu) na ihe ọla ndị ọzọ nwekwara ike ịhọrọ.

Silicon nitride ceramic bearings: A na-eji silicon nitride (Si3N4) mee ihe mgbanaka na-agbagharị agbanaka, nke nwere oke ọsọ na ikike ibu karịa bearings ZrO2, ma nwee ike ime mgbanwe na okpomọkụ dị elu.

Silicon carbide ceramic bearings: Silicon carbide (SiC) ihe a na-eji maka mgbanaka na ihe na-atụgharị, nke nwere njirimara mara mma dị ka ike siri ike, na-eyi nguzogide, isi ike na obere esemokwu.

Na mgbakwunye, a na-ahazi bearings seramiiki site na nhazi gụnyere:

 

All-seramiiki bearings: A na-eji ihe seramiiki mee ihe mgbanaka na ihe na-atụgharị, na onye na-ejide ya dị na nhọrọ dịgasị iche iche, dị ka polytetrafluoroethylene (PTFE), naịlọn 66, polyetherimide (PEEK), polyimide (PI), igwe anaghị agba nchara ma ọ bụ aluminom ụgbọ elu pụrụ iche, wdg. .

 

Ngwakọ seramiiki ngwakọ: a na-eji mgbanaka ahụ mee ihe ígwè dị ka ihe na-ebu ígwè ma ọ bụ igwe anaghị agba nchara, na ihe na-agbagharị agbagharị bụ bọọlụ seramiiki, nke nwere àgwà magburu onwe ya dị ka njupụta dị ala, ike siri ike, na-eyi nguzogide, isi ike na obere esemokwu, na ndụ ọrụ bụ. ukwuu gbatịa.

 

A na-ekewa beri seramiki site na ngwa, gụnyere:

Igwe na-agba ọsọ dị elu: a na-ejikarị ya na ngwa ngwa ngwa ngwa, ngwa ngwa dị elu, na-eji ike dị ala, nkwụsị nrụgide dị elu, ịdị arọ dị arọ, na oke okpomọkụ.

Igwe ọkụ dị elu: ejiri ya na akụrụngwa okpomọkụ dị elu, ọ nwere ike iguzogide okpomọkụ dị elu nke 1200 Celsius ma nwee ezigbo mmanye onwe ya.

Bearings na-eguzogide corrosion: ejiri ya na gburugburu ebe ọrụ chọrọ ịnagide mgbasa ozi siri ike dị ka acid siri ike na alkalis, ngwakọta organic ma ọ bụ mmiri oké osimiri.

Mgbochi ndọta: na-abụghị magnetik, eji na demagnetization akụrụngwa, nkenke ngwa na ngwa ndị ọzọ, n'ụzọ dị irè na-ezere arc mmebi akụkụ.

Igwe ọkụ eletrik na-ekpuchi ọkụ: akụkụ ndị nwere nnukwu resistivity na nkwụsị nke arc dị irè, nke a na-ejikarị na ngwa ike.
