• Double Row Tapered Roller Bearing Railway Bearing Code

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.
