The LL (labyrinth-lip) seal design is based on a low-friction rubber seal principle that is applied to TBU and CTBU designs. The main features are a combination of labyrinth, lip and flinger elements and improved protection against contaminants to extend bearing service life. The frictional moment can be reduced by up to 75%, compared to a garter seal arrangement. As a consequence, the bearing operating temperature is reduced by 20 ℃, which contributes to longer grease life and energy savings. Results from the seal test, which evaluates water and dust exclusion, confirmed that the design is very effective in excluding contaminants. Long-term endurance tests have successfully been conducted under very severe operating conditions.

Railway Axle Bearings are subject to radial impact loads caused by rail joints, switches and sometimes wheel flats, as well as to the static and dynamic radial loads of vehicle weight. They are also liable to receive axial loads generated by lateral movement as trains run on curved rails or in a snaking motion. All of these loads together form complex combinations that act on axle bearings.Axle bearings must therefore be designed on the basis of not only dimensional requirements of the axle journal and bearing box geometry, but also these complex load conditions. Additionally, as axle bearings play a critical role in the safety of railroad operation, they are periodically disassembled for inspection.Roller bearings, including tapered roller bearings, spherical roller bearings and cylindrical roller bearings, are increasingly being selected to replace plane bearings in rolling stock axles based on the particular merits of each type.

Garter seal as mentioned, the first 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. TEDRAIL can offer SKF seals according to AAR Manual of Standards and Recommended Practices Section H-Ⅱ［S723］-Roller Bearing Manual .TEDRAIL can also provide special LL seal designs for inch size TBUs that generate much lower friction
