NN3012KTN/SP Super-chaiyo Kaviri-mutsara cylindrical roller inobereka
Aya mabearings saka akanyatsokodzera muchina maturusi spindles uko kurongeka kwekutakura kunofanirwa kugarisa inorema radial mitoro uye kumhanya kwakanyanya, uku ichipa huwandu hwakanyanya hwekuomarara, kaviri mitsara mabearings akanyanya kukodzera kurema mitoro.
Kaviri-mutsara cylindrical roller bearings ane zvimiro zviviri: cylindrical inner bore uye conical inner bore (iyo inotakura rear code plus K). Iyo conical yemukati gomba inogona zvakare kuita basa reiyo micro-kugadziriswa kweiyo clearance, uye inogona kurerutsa chimiro cheiyo yekumisikidza mudziyo uye kufambisa kuisirwa uye disassembly.
Inowanzo shandiswa double row cylindrical roller bearings ine marudzi anotevera: NN series, NNU series, uye NNF series.Tolerances: SP, UP, SP uye UP ye1:12 tapered bore.
