Tapered roller bearing units (TBUs) consist of two inner rings, one common outer ring, two tapered roller and polymer cage assemblies, a central spacer, grease fill and two sealing systems. Further components like lateral spacers, backing rings and end caps with their locking device can be added to the assembly as well as components based on specific customer requests.

Tapered roller bearing units were designed to replace plain bearings. These inch size TBU designs had to match the existing relatively long journal dimension. This design enables the integration of a seal wear ring on both sides where the garter seals are riding. AAR has standardized these garter seals and seal wear rings, which are interchangeable with components from different bearing manufacturers. Today, SKF offers special LL seal designs for inch size TBUs that generate much lower friction.
