Abubuwan da aka yi da zirconia na yumbu:

Ana amfani da kayan yumbu na Zirconia (ZrO2) don zoben ɗaukar kaya da abubuwan birgima, yawanci ana amfani da polytetrafluoroethylene (PTFE) don masu riƙewa, kuma ana iya zaɓar nailan mai ƙarfi na gilashi 66 (RPA66-25), robobi na injiniya na musamman (PEEK, PI) ko bakin ƙarfe (AISI SUS316) da tagulla (Cu) da sauran kayan ƙarfe.

Bearings na yumbu na Silicon nitride: Zoben bearings da abubuwan birgima an yi su ne da silicon nitride (Si3N4), wanda ke da saurin gudu da ƙarfin kaya fiye da bearings na ZrO2, kuma yana iya daidaitawa da yanayin zafi mafi girma.

Bearings na yumbu na silicon carbide: Ana amfani da kayan silicon carbide (SiC) don zoben ɗaukar kaya da abubuwan birgima, waɗanda ke da kyawawan halaye kamar babban tauri, juriyar sawa, tauri da ƙarancin gogayya.

Bugu da ƙari, ana rarraba bearings na yumbu ta hanyar tsari, gami da:

 

Bearings na yumbu: An yi zobe da abubuwan birgima da kayan yumbu, kuma mai riƙewa yana samuwa a cikin zaɓuɓɓuka iri-iri, kamar polytetrafluoroethylene (PTFE), nailan 66, polyetherimide (PEEK), polyimide (PI), bakin ƙarfe ko aluminum na musamman na jirgin sama, da sauransu.

 

Hybrid yumbu hali: zoben an yi shi ne da kayan ƙarfe kamar ƙarfe mai ɗaukar kaya ko bakin ƙarfe, kuma abin birgima ƙwallon yumbu ce, wadda ke da kyawawan halaye kamar ƙarancin yawa, tauri mai yawa, juriyar lalacewa, tauri da ƙarancin gogayya, kuma tsawon lokacin sabis ɗin yana da tsawo sosai.

 

Ana rarraba bearings na yumbu ta hanyar amfani, gami da:

Bearings masu sauri: galibi ana amfani da su a cikin kayan aiki masu sauri da daidaito, tare da ƙarancin sassaucin ƙarfi, juriya mai ƙarfi, nauyi mai sauƙi, da kuma yanayin zafi mai yawa.

Mai ɗaukar zafi mai yawa: ana amfani da shi a cikin kayan aiki masu zafi mai yawa, yana iya jure yanayin zafi mai yawa na 1200°C kuma yana da kyakkyawan aikin shafawa mai kai.

Bearings masu jure wa tsatsa: ana amfani da su a cikin yanayin aiki waɗanda ke buƙatar jure wa matsanancin ƙarfi kamar acid mai ƙarfi da alkalis, gaurayawan halitta ko ruwan teku.

Maganin hana maganadisu: ba shi da maganadisu, ana amfani da shi wajen lalata maganadisu, kayan aikin da suka dace da sauran kayan aiki, yana guje wa lalacewar sassan baka yadda ya kamata.

Bearings masu rufi da wutar lantarki: sassan da ke da juriya mai ƙarfi da kuma ingantaccen fashewar baka, waɗanda galibi ana amfani da su a cikin kayan aikin wutar lantarki.

Vacuum bearing: kyakkyawan aikin shafa man shafawa, wanda ake amfani da shi a cikin yanayin injin mai matuƙar ƙarfi.
