ASTM B271 C95500 tooj liab-raws li tus kheej-lubricating inlaid graphite bearings
ASTM B271 C95500 tooj liab-raws li nws tus kheej-lubricating Graphite Insert Bearings yog tus kheej-lubricating, tsis muaj txij nkawm, muaj ib tug centrifugally cam khwb cia tooj liab alloy (ASTM B271 C95500) rau bearings nrog ib tug bore txoj kab uas hla ntau tshaj 180 mm, los yog ntawm ib tug nruam nruam alloy (ASTM B505 C95500) rau bearings nrog ib txoj kab uas hla tsawg dua 180 hli, hnav-resistant, nrog ib tug khoom lubricant uas muaj graphite sau rau ntawm nws qhov chaw tiv tauj thiab qauv raws li lub npe hu ua "macro-distribution txoj cai" thiab cov hom kev txav tus kabmob yuav raug rau.
Cov bearings yog muab nrog 15 mus rau 20µm khiav-hauv zaj duab xis, uas yog los xyuas kom meej tias cov khoom lubricant raug xa mus rau cov khoom mating thaum thawj lub zog.
Lawv yuav tsum muaj lub peev xwm zoo li qub thiab muaj zog, ruaj khov coefficient ntawm kev sib txhuam, tsis muaj "stick-slip" cuam tshuam, ua rau corrosion-resistant, insensitive rau av, thiab haum rau siv hauv dej, roj lossis roj.
Rau cov bearings nrog ib txoj kab uas hla ntau dua 200mm, qhov kam rau ua yuav tsum tau xam los ntawm peb daim ntawv thov engineering pab neeg raws li qhov tsis muaj ntawm txhua daim ntawv thov.
Koj daim ntawv thov tshwj xeeb yuav xav tau cov lus qhia tshwj xeeb mounting.
