¡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).
