Iimpawu ● Ibhola ye-angular contact ball bearing kunye ne-raceway yeringi yangaphakathi kunye neringi yangaphandle inokuqhagamshelana nge-angle kwicala le-radial.Xa isetyenziswe yodwa, umthwalo we-axial ukhawulelwe kwicala elinye, kwaye ufanelekile kumthwalo odibeneyo womthwalo we-axial kunye nomthwalo we-radial.● Ngenxa yokuba le bherethi ine-angle yoqhagamshelwano, icandelo lamandla e-axial liveliswa xa i-radial load isebenza.Ngoko ke, ngokuqhelekileyo isetyenziswe ngendlela ye-symmetry okanye ukudibanisa kumacala omabini e-shaft.● Kukwakho neentlobo ezisebenzisa iibhola zeceramic.I-angle yoqhagamshelwano Kukho iindidi ezimbini ze-angle yoqhagamshelwano, i-15 ° kunye ne-25 °.I-15 ° isetyenziselwa ukusetyenziswa kwesantya esiphezulu.I-25 ° ifanelekile kwiimeko apho kufuneka ukuqina kwe-axial.Ikheji yenziwe ngepolyamide njengesiqhelo.Nceda usebenzise ikheji yepolyamide engaphantsi kwe-120°.Ukuchaneka komda kunye nokuchaneka okujikelezayo kuhambelana neklasi ye-JIS yesi-5 okanye yesi-4. Nceda ujonge kwiphepha lesi-7. Ukulayisha kwangaphambili ● Seta iindidi ezi-4 zesixa esiqhelekileyo sokulayisha kwangaphambili.Khetha ukulayisha kwangaphambili okufunekayo ngokusekelwe kwiikhrayitheriya zokukhetha kwitheyibhile esekunene.● Jonga kwiphepha le-16 ukuya kwele-18 ngesixa esiqhelekileyo sokulayisha kwangaphambili kuthotho nobukhulu.

Ukudibanisa Ukusetyenziswa kwe-multi-column assembly, nceda ubhekisele kumaphepha e-12 ukuya ku-13. Uhlobo lwebhola ye-Ceramic Ukuze unciphise amandla e-centrifugal yebhola ngexesha lokujikeleza kwe-high-speed, ibhola ye-ceramic ene-density ephantsi kunentsimbi yokuthwala isetyenzisiweyo.● Jonga kwitheyibhile engezantsi ngeempawu ezahlukeneyo zeseramiki kunye neentsimbi zokuthwala.● Yongeza "SH6-" ekuqaleni kwenani lemodeli yeebheringi usebenzisa iibhola zeceramic.● Ukulayisha kwangaphambili kunye ne-axial rigidity malunga namaxesha e-1.2 yohlobo lwebhola yentsimbi.Isimboli yokulayisha kwangaphambili umgangatho we-E (ukulayisha kwangaphambili okuncinci) Thintela ukungcangcazela koomatshini kunye nokuphucula ukuchaneka L (ukulayisha kwangaphambili ukukhanya) Isantya esiphezulu (ixabiso le-dmn le-500,000) isenobungqongqo obuthile M (ukulayisha kwangaphambili okuphakathi) Isizukulwana sikhaphukhaphu kunesantya esisezantsi Ukuqina H kunye nesantya esiphezulu. ukulayisha kwangaphambili (umthwalo onzima) kuvelisa ubungqongqo obukhulu kwizantya ezisezantsi.
