FAG bearings are mass-produced mechanical components, are strict and manufacturing precision, a high level of technical specialization, so for the vast majority of readily available assortment, purchased should be more cost-effective than repair, only in the following cases, bearing repair issues, namely:
　　(1) bearing a large number of the same model used in large factories, its failure mainly for rolling surface wear, fatigue and fretting wear, in particular damaged part many cages or rollers, rings or washers still have fixed values;
　　(2) large and oversize bearings, the brink of failure parts failure or who may have had no major injuries, or valuable bearing must be sought to extend its useful life;
　　(3) some are hard to purchase assortment, no spare parts had to be repaired after failure, in particular, FAG bearings;
　　(4) bearing minor damage, such as inventory generated minor scale, as well as slight micro-abrasion during transport, such repair easy and discard it.
　　In addition to economics, bearing repair also has its technical, this requires repair is well understood by bearings the corresponding technical requirements and bearing and parts on the structure, process and material characteristics, effects of otherwise difficult to ensure that the bearing repairs are eligible.
　　Economic benefits of a bearing repair
　　Generally speaking, bearing varieties of small volume, high price for a single bearing, or bearing simple structure. Large size, relatively lower repair costs, economic efficiency is higher.
　　In addition, to monitor the functioning of the bearing, until there is a plan in the bearing failure to repair it, can receive twice the effect. Follow the rational process, efficient repair equipment and tools, as well as help professional bearing factory, helped to improve economic efficiency.
　　B, the advantages of cooperation with the professional bearing company
　　User repair bearings business, such as professional bearing company cooperation can be achieved, will probably yield the following benefits:
　　(1) clear repair all the technical requirements for the operation of, and repairs to ensure the overall quality of bearings;　
　　(2) can take advantage of many of the bearing factory specialized experience, these experiences can reliably, efficiently, and cost effectively meet the technological requirements;
　　(3) can order the SIN card bearing enterprise from a professional mold, borrowing in the repair business, may be more economical and save a lot of trouble;
　　(4) can contribute to the professional bearing company orders such as cage, rolling elements, rivets, and other accessories, which can make repair work easy and convenient and economical.
