Spherical Roller Bearing
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically, these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a (barrel like) profile that makes them appear like cylinders that have been slightly over-inflated.

Unit Bearing
A unit bearing is a completely sealed, non-serviceable unit. When the bearings wear out, you have to replace the entire live spindle. If we look just at the spindle and bearing assemblies, the advantage of a unit bearing is that you never need to pack the wheel-bearings with grease or replace seals.
