    DB—duplex–back to back. DF—duplex–face to face. DT—duplex–tandem. DBT, DFT, DTT—triplex set. DBTT, DFTT, DTBT, DTFT— quad set. NTN standard angular contact bearings have 30º or 40º contact angles. For normal loads, the 30º angle bearings (no P/N suffix) are usually used. For high axial load applications, 40º

    combining either DB or DF series bearings. DT series bearings can also be used in various arrangements to achieve uniform load distribution. All BNT type bearings are flush ground, but other angular contact ball bearing series are not. If it is necessary to flush grind any of these other bearings, please consult NTN
