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.
