The inner ring with rollers is often called the inner sub-assembly. Separable design of tapered roller bearings has different advantages during assembly and handling of the bearing. Rolling elements in the tapered roller bearing operate on tracks oblique to the bearing axes. The projection lines of all the tapered surfaces meet at a common point on the bearing axis, what ensures proper rotation of rollers on the tracks. |
Tapered roller bearings consist of two inseparable elements: the outer ring, which contains one of the oblique bearing tracks (the outer track) and the inner ring, on the track of which the cage with rolling elements is mounted. Rolling elements in this type of bearing are shaped as cones with truncated vertices. Judging by their appearance they resemble rollers or rolls, for that reason they are commonly called roll bearings or roller bearings. Under normal operation conditions the inner ring, the outer ring and rollers carry the load, whereas the cage separates and holds the rollers.
