Feature:
This bearing is mainly used to bear the combined radial and axial load dominated by radial load. Generally, it is not suitable to bear the axial load alone. Its inner race surface, outer race surface and the apex of each conical surface of the roller rolling surface intersect at a point on the bearing centerline. It is suitable for bearing heavy load and impact load.
