Silicon Nitride Balls Si3N4 Ceramic Bearing Pob
Lub linear expansion coefficient ntawm silicon nitride ceramic pob yog 3.2 × 10-6 / K, uas yog yuav luag 1/4 ntawm cov kabmob steel pob. Tus kheej-lubricating zog ntawm silicon nitride ceramic pob bearings tuaj yeem daws cov pa phem los ntawm qhov nruab nrab lubricating thiab qhov tsis yooj yim ntawm kev ntxiv. Tshuaj tiv thaiv, txhua yam muaj zog, tawg toughness, tsawg thermal conductivity. Daim ntawv thov teb: composite bearings, mechanical seals, tshuaj twj, nozzles, nws pib qhov chaw, tshav kub exchanger qhov chaw, khoom nqus tsev vacuum, thiab lwm yam.
Silicon nitride ceramic pob tuaj yeem siv rau ntau yam bearings nrog rau kev ua tau zoo: high-speed bearings, high precision bearings, nqus bearings, siab / qis kub bearings, tsis-magnetic bearings, high precision pob ntsia hlau; Kuj tseem siv tau rau hauv cov twj tso kua mis, lub twj tso kua mis kub, lub twj tso kua mis metering siv los ua lub pob valve, ntsuas pob.
