RepairSince the fluid lubrication bearing supports high-speed and high-load rotating rotor, the white metal of the bearing would be damaged by the high vibration or the high metal temperature as well as by the frequent start-up and shutdown operation. If you remove this damaged white metal and then re-babbitt with the new white metal, you can use the bearing as if it were new. When repairing the bearing like this, the design data of the bearing have to be derived correctly in order to re-machine the bearing to get the performance as same as the new one.

Turbolink has outstanding design capabilities and long manufacturing experiences that can provide the technology to repair the damaged bearings successfully as like a new. Furthermore our laser cladding technology, which was recently developed, will provide you the advantage of the improved bonding strength of white metal by more than 50% compared to the existing technology (centrifugal and gravity casting or welding).

ReplacementTurbolink can supply any kind of spare bearings reverse engineered, which customers require.

Even though spare bearings are needed in the actual field, they are completely purchased at a very expensive price from the equipment supplier because most customers have no bearing drawing. Turbolink can manufacture and supply spare bearings with the same or better performance through the reverse engineering, even if the customer does not have a drawing. Turbolink's long design experience and successful application capabilities can provide you high quality spare bearings at an affordable price

RetrofitThe machine can be stopped in emergency for checking the bearing during the operation when the bearing metal temperature or the vibration is too high.Problems such as temporary operation mistakes can be easily resolved, but high vibration or high temperature from the initial operation is most likely caused by poor design of the bearing. In this case, you will be paying tremendous loss-time and stresses because of repeated problems unresolved. Turbolink has a lot of experience in successfully improving the bearing design to solve the high temperature and unstable vibration of the bearings for power plant turbines. If you are suffering from the problem of the bearings temperature or vibration yet, please do not hesitate to contact our excellent Turbolink engineers.
