¡Since the distance "l" between the cone pressure apexes of bearing is large, the load capacity of the moment load is high. ¡Permissible slant angle is small. These bearings support the radial loads and both direction of axial loads. Back-to-back duplex arrangement. (Code: DB). Face-to-face duplex arrangement. (Code: DF)..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.6. DUPLEX ARRANGEMENT. DB: Duplex pair, back to back mounting. DF: Duplex pair, face to face mounting. DT: Duplex pair, tandem mounting. G: Single bearings, flush ground universal mount for DB, DF and DT arrangement.
