KOYO bearings, the mass production of mechanical parts and the manufacturing accuracy requirements are very strict, so for the vast majority of bearing varieties readily available, it should be more economical to buy than repair, and only in the following cases before considering the bearing repair issues, namely:


(1) a lot of the same type of bearings used in large factories, the failure mainly in the form of a rolling surface of the wear, fatigue, or micro-abrasion, especially the damaged parts cage or rolling element rings or gaskets still repair value;


(2) large and extra large bearing on the brink of failure Despite the failure of parts no major damage, or a valuable bearings must try to extend its effective use of;


(3) is really difficult to buy into the bearing varieties, failure of spare parts had to repair, especially imports of bearings;


(4) bearing minor injuries, such as inventory period minor water rust, and the transport process to produce a slight micro abrasive, such repair easy gesture.


In addition to the economy, bearing repair technical, which requires the repairer to fully understand the bearing of the corresponding technical requirements, bearings and parts thereof in the structure, process and material characteristics, it would be difficult to ensure that the bearing repair in line with the required effect.
