Double row Silinder Roller Bearing

Terdapat dua jenis struktur double row silinder roller bearings: lubang dalaman silinder dan lubang dalaman kon. Galas jenis ini mempunyai kelebihan struktur padat, ketegaran yang tinggi, kapasiti beban yang besar dan ubah bentuk kecil selepas pemuatan, dan lain-lain. Ini amat sesuai untuk sokongan spindle alat mesin. Ia boleh dibahagikan kepada dua jenis: siri NN dan siri NNU. NN siri roller galas silinder mempunyai bebibir berganda pada cincin batin, tetapi tiada flange pada cincin luar. Galas jenis NNU mempunyai bebibir berganda pada cincin luar tetapi tidak mempunyai flange pada cincin batin. Kedua-dua galas tidak mengehadkan anjakan paksi relatif di antara aci dan perumahan dan boleh digunakan sebagai galas bukan kedudukan.
