Muaj ib qho concave spherical nto nyob rau hauv nruab nrab ntawm lub phaj qis, uas sib haum mus rau convex nruab nrab phaj.Muaj ib qho arc-shaped PTFE phaj lined ntawm ob.Tus kheej kheej nto swb nrog nws kom txaus siab qhov kev sib hloov ntawm lub nqaj kawg;stainless hlau phaj ntawm lub rooj zaum saum phaj yog nyob rau hauv nruab nrab steel phaj.Lwm lub phaj tetrafluoroethylene yog qhov thib ob zawv zawg saum npoo, uas ua tiav qhov ncab thiab braiding txav ntawm cov nqaj vim muaj ntau yam ntawm qhov kub thiab txias.
1. Lub pob bearing xa cov quab yuam los ntawm tus kheej kheej, thiab tsis muaj qhov tshwm sim quab yuam, thiab cov tshuaj tiv thaiv quab yuam ua rau cov pob zeb sib xws;
2. Lub pob bearing paub txog cov txheej txheem kev sib hloov ntawm cov kabmob los ntawm kev zawv zawg ntawm kheej kheej polytetrafluoroethylene phaj.Lub rotating torque yog me me, uas yog tshwj xeeb tshaj yog haum rau cov kev cai ntawm lub ces kaum.Lub kaum sab xis tsim tuaj yeem ncav cuag ntau dua 0.05rad;
3. Cov kabmob muaj qhov ua haujlwm zoo ib yam ntawm txhua qhov kev taw qhia, uas yog tsim rau cov txuas hniav dav thiab nkhaus;
4. Cov kabmob tsis tas yuav tsum tau ua los ntawm cov roj hmab, thiab tsis muaj kev cuam tshuam ntawm roj hmab kev laus ntawm kev sib hloov ntawm cov kabmob.Nws yog tshwj xeeb tshaj yog haum rau cov cheeb tsam uas tsis tshua muaj kub.
