■Features: Designed so that the raceway surfaces of the inner and outer rings and the apex of the conical surface of the rollers meet at one point on the center line of the bearing, these bearings are suitable for applications where heavy loads or impact loads are applied. They can support axial load in one direction, as well as radial load.
