mainly used to bear radial load, but also to be capable of an axial load direction, aligning good performance that can compensate for axial bending force or an improper installation of the coaxial error and it applies to heavy loads occasions.

Aligning a cylindrical roller bearing holes with conical holes and tight sleeve, three common structure. If the cross-section shape by roller can be divided into symmetrical and asymmetrical shape-spherical roller ionizing structure. Symmetric shape spherical roller bearings than non-symmetrical shape to bear a greater axial load capacity and longer service life. To improve bearing lubrication, aligning roller bearings can be made from the outer ring to ring tank and the ring with three hole.
