Railway bearings supplier CTBU150
train bearing CTBU150x260x160
CTBU150x260 x160 Bearings for high speed railways.The bearings run at speeds above 200km/h and require high load carrying capacity.
As the double row tapered roller bearings have a better sealing structure and the clearance has been adjusted before installation,this type of bearing is mostly used for high speed railways.

Structure at a glance
1. Generally, this bearings consist of an end cap, cap screws, a locking plate for fastening the end cap, a seal wear ring, a
doublerow tapered roller bearing and a backing ring. The latest variation has a backing ring that also serves as a seal wear ring.
2. When the axle end needs to be exposed for inspection or re-machining of the wheel, it can be exposed easily by loosening the cap screws and removing the end cap. A recent variation incorporates a smaller rubber cover designed to further ease access to the end of the axle.
3. Oil seals, mounted in seal cases, are press-fitted onto both ends of the outer ring and are in contact with the seal wear rings with a specified interference and pressure. The seals are spring-loaded contact seals. They are capable of preventing grease leakage and the intrusion of water and foreign matter into the bearing. The seal packing is made of nitrile or acrylic rubber in most cases, although it may be made of fluoric rubber for high-speed applications such as in Shinkansen trains.

4. An amount of grease equivalent to approximately one-half to one-third of the bearing’s internal volume, including seal lips,is prepacked in the bearing. No grease replenishment is necessary for the duration of the bearing’s service life. Grease with NLGI consistency number 2 is used for axle bearings. Lithium or sodium grease is most often used, though other kinds of grease such as lithium-calcium compound grease or urea-based grease may be used depending on bearing conditions like speed, load and maintenance frequency.
5. The mounting and dismounting of bearings is performed by press-fitting or press-pulling using special-purpose tools.
The press-fitting operation is controlled by the amount of interference between the outside diameter of the axle journal
and the bore diameter of the bearing’s inner ring, as well as by the load applied from the press-fitting.
6. For the assembly of bogies with axles supported by bearings, saddle-type adapters are used instead of the bearing boxes commonly used for ordinary bearings. The use of such adapters can reduce the weight of the bogie and make assembly work easier.

Our company
Jinan Kaiming Bearings commenced operations as the first Chinese manufacturer of rolling bearings back in 1992. Ever since, we have been continuously expanding and improving not only our product portfolio but also our range of services for various industrial sectors.
In this context, we develop technologies in the fields of rolling bearings, linear systems, components for the automotive industry and mechatronic systems. Our research and production facilities in Europe, Americas and Asia are linked together in a global technology network. Here we concentrate not only on the development of new technologies, but also on the continuous optimisation of quality – at every process stage. Among other things, our research activities include product design, simulation applications using a variety of analytical systems and the development of different steels and lubricants for rolling bearings.
