A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment.

Typically these bearings support a KOYO dac3055w Bearing rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.

Spherical Roller Bearing. Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction.
