China Railway European Bearing for Rolling Stock

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.

TEDRAIL supply all the range of railway axle bearings, such as Tapered Bearing Units (TBU), Compact Tapered Bearing Units (CTBU) for the applications including:
Ø bearings of the axles for the goods wagons, passenger wagons, electric and diesel locomotives, electric and diesel engine vehicles and motor units which is AAR approved.
Ø gear boxes, driving traction motors and generators, motors of compressors (air pumps) and drives of ventilators, actuators and charging generator of the electric and diesel locomotive engines.
Type: TBU 130
Features:
·New optimized polymer cage
·Improved raceway micro-geometry
·Integrated labyrinth lip (LL) low friction rubber seal
·High-performance grease.
The optimized cage is made from reinforced polymer and has proven excellent in operation, particularly in terms of safety and performance.
