Taper roller bearing can support axial forces and radial forces. The inner and outer rings of the raceways are segments of cones. The rollers are tapered in a way that the surfaces of the raceways, and the roller axles would all meet at a common point on the axis of the bearing. This makes it so that the motion of the cones stay coaxial and that there are no sliding motions between the raceways and the outer dimension of the rollers. Pairs of a taper roller are commonly used in cars and vehicle wheel bearings where they are required to simultaneously cope with large horizontal and vertical forces. Common applications are used in agriculture, construction, gearboxes and engine motors.
