SKF taper roller bearings can be divided into single row and double row taper roller bearings.and Four row tapered roller bearings. Tapered roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26, 000 tapered roller bearing combinations in single, double and four-row tapered roller bearing configurations. Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.
