Musamman, rarrabuwa nayumbu bearingsta kayan sun haɗa da:

Zirconia yumbu bearings:

Zirconia (ZrO2) kayan yumbura ana amfani dasu don ɗaukar zobba da abubuwan mirgina, yawanci ana amfani da polytetrafluoroethylene (PTFE) don masu riƙewa, da fiber gilashin ƙarfafa nailan 66 (RPA66-25), robobin injiniya na musamman (PEEK, PI) ko bakin karfe (AISI) SUS316) da tagulla (Cu) da sauran kayan ƙarfe kuma ana iya zaɓar su.

Silicon nitride yumbu bearings: The bearing zobba da mirgina abubuwa da aka yi da silicon nitride (Si3N4), wanda yana da mafi girma gudun da kuma loading fiye da ZrO2 bearings, kuma zai iya daidaita zuwa mafi girma yanayin zafi.

Silicon carbide yumbu bearings: Silicon carbide (SiC) kayan ana amfani dashi don ɗaukar zobba da abubuwan birgima, waɗanda ke da kyawawan halaye irin su babban taurin, juriya, tsauri da ƙarancin gogayya.

Bugu da ƙari, ana rarraba bearings yumbura ta tsari wanda ya haɗa da:

 

Dukkanin yumbu bearings: Ring da mirgina abubuwa da aka yi da yumbu kayan, da kuma retainer yana samuwa a cikin wani iri-iri zažužžukan, kamar polytetrafluoroethylene (PTFE), nailan 66, polyetherimide (PEEK), polyimide (PI), bakin karfe ko musamman jirgin sama aluminum, da dai sauransu .

 

Hybrid yumbura mai ɗaukar nauyi: zobe an yi shi da kayan ƙarfe kamar ƙarfe ko bakin karfe, kuma abin birgima shine ball na yumbu, wanda ke da kyawawan halaye kamar ƙarancin ƙarancin ƙarfi, ƙarfi mai ƙarfi, juriya, tsauri da ƙarancin gogayya, kuma rayuwar sabis shine. sosai mika.

 

An rarraba bearings yumbu ta aikace-aikace, gami da:

Ƙaƙwalwar hanzari: yawanci ana amfani da su a cikin sauri, kayan aiki mai mahimmanci, tare da ƙananan ƙarfin ƙarfi, ƙarfin juriya, nauyin haske, da yanayin zafi mai yawa.

Ƙunƙarar zafi mai zafi: ana amfani da shi a cikin kayan aiki mai zafi, yana iya tsayayya da zafi mai zafi na 1200 ° C kuma yana da kyakkyawan aikin kai.

Bearings masu jurewa lalata: ana amfani da su a cikin wuraren aiki waɗanda ke buƙatar jure wa matsananciyar kafofin watsa labarai kamar su acid mai ƙarfi da alkalis, gaurayawan halitta ko ruwan teku.

Anti-Magnetic bearing: ba Magnetic, amfani da demagnetization kayan aiki, daidaitattun kayan aiki da sauran kayan aiki, yadda ya kamata kauce wa baka rushe sassa.

Abubuwan da aka keɓe na lantarki: sassan da ke da babban juriya da rushewar baka mai tasiri, waɗanda galibi ana amfani da su a cikin kayan wuta.

Vacuum bearing: kyakkyawan aikin mai mai da kai, ana amfani da shi a cikin mahalli mai girman gaske.
