Railway Bearing Tapered Roller Bearing Units Train Bearing 

Tapered roller bearing units (TBUs) consist of two inner rings with a tapered roller and polymer cage assembly, a common outer ring, a central spacer, two sealing systems and a grease fill. 

The classic TBU for American freight car bogies is designed with inch size dimensions following the standards of the Association of American Railroads (AAR).

For new freight cars with increased cargo, inch size compact tapered roller bearing units (CTBUs) are used. The sealing system of the CTBU consists of two parts: a (stationary) seal that is anchored in the outer ring and a flinger ring that is fitted directly on the inner ring shoulder. This design offers increased reliability.
