Cov menyuam bearings feem ntau muaj plaub ntu: lub nplhaib sab nraud, lub nplhaib puab, dov cov ntsiab lus (rollers), thiab lub tawb.
Cov nplhaib sab nrauv thiab sab hauv feem ntau yog ua los ntawm siab -carbon chromium bearing steel, muab cov lem rau cov menyuam; cov khoom dov (cylindrical, tapered, lossis spherical rollers) yog cov khoom tseem ceeb uas ris lub nra; lub tawb yog siv los sib cais cov ntsiab lus dov, tiv thaiv lawv los ntawm kev sib tsoo, thiab coj lawv txoj kev txav mus los.
Paub meej Composition thiab Function:
Sab nrauv thiab sab hauv Rings: Ua los ntawm cov kabmob steel xws li GCr15, tom qab kev kho cua sov, lub hardness ncav cuag HRC58-62, kom ntseeg tau tias hnav tsis kam thiab qaug zog. Lub nplhaib puab yog feem ntau haum rau lub ncej, thaum lub nplhaib sab nrauv yog tsau rau cov kabmob vaj tse.
Rolling Elements: Cov dov cov ntsiab lus ntawm cylindrical roller bearings yog cylindrical, thiab cov kab kev sib txuas tsim ua rau lawv cov load- nqa peev ntau dua li ntawm pob bearings. Cov ntaub ntawv yuav tsum sib phim lub hardness ntawm lub puab thiab sab rings, thiab cov nto roughness yuav tsum tau tswj nyob rau hauv Ra0.05μm kom txo kev sib txhuam.
Cage: Steel tawb (xws li SPCC) yog siab - lub zog thiab haum rau siab - daim ntawv thov ceev; nylon tawb yog hnav thiab corrosion-resistant. Qhov yuam kev ntawm lub tawb qhov sib txawv yuav tsum tsawg dua los yog sib npaug li 0.1 hli kom ntseeg tau tias cov menyuam sib txawv.
