    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 angle bearings are available (P/N suffix B). Both of.

  • Angular Contact Ball 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 Engineering. Offset B. Front face. Back face. Offset A.
