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

With a fixed outer ring and a sliding inner ring, these bearings are commonly found in electric motors.

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 with high levels of reliability.

This bearing has the designation NU for easy identification.
