Single-row tapered roller bearings are able to withstand high combined radial and axial loads. The axial loads are borne in only one sense and, in addition, the radial loads generate an induced axial load in the bearing. This induced load must be counteracted and therefore these bearings are arranged in opposing pairs, so that each one can be offset against the other
These bearings are easy to disassemble. On the one hand, we have the external unit (ring) and on the other the inner unit (cone + cage + rollers).
Another important characteristic of these bearings is their ability to absorb slight angular misalignments between the inner and outer rings, basically due to the fact that the internal design of the contact between the rollers and the raceways has been modified, which also prevents the concentration of stresses on the edges of these raceways.
