What are the features and benefits of bearings with a fixed outer ring and sliding inner ring?

With a fixed outer ring holding the rolling elements and a sliding inner ring, these bearings are able to carry a high radial load at mid-speed, but are not able to take any axial load in either direction. 

Excellent running characteristics make this bearing an efficient choice for electric motors and has high levels of reliability.
