Spherical roller bearings are designed for applications where there is severe misalignment, either mounting or shaft runout, as well as relatively heavy radial loads and some axial loads in either direction.
They are also extremely resistant to shock loads, and their self-aligning feature allows full-capacity loads with shaft deflection. Their purpose is very similar to double row self-aligning ball bearings, but spherical roller bearings are designed to carry heavier loads but are stronger at lower top speeds.
