What kind of rolling bearing has repair value, and what is the best way to repair it?
Rolling bearings are mass-produced mechanical parts, and the manufacturing accuracy requirements are very strict, and the degree of technical specialization is very high. Therefore, for most of the easy-to-buy bearing varieties, it should be more cost-effective to buy than repair, only in the following cases Before considering the problem of bearing repair:
(1) A large number of bearings of the same type used in large factories mainly fail in the form of wear on the rolling surface, fatigue or fretting abrasion. In particular, the damaged parts are mostly cages or rolling elements, while the ferrules or washers are still repaired. value;
(2) Large and extra-large bearings are on the verge of failure or have failed but the parts have not been seriously damaged, or valuable bearings must try to extend their useful life;
(3) Certain bearing types that are really difficult to buy have to be repaired without spare parts after failure, especially imported bearings;
(4) Bearings are slightly damaged, such as slight water rust during the inventory period, and slight fretting abrasion during transportation. It is a pity that such cases are easy to repair and discard.
In addition to economy, bearing repair has its technical nature, which requires the repairer to fully understand the corresponding technical requirements of the bearing, and the characteristics of the structure, process and material of the bearing and its parts. Otherwise, it is difficult to ensure that the repair of the bearing is effective. Desirable effect.
1. Economic benefits of bearing repair
Generally speaking, the variety of bearings is small, the quantity is large, the price of a single bearing is high, or the structure of the bearing is simple. The larger the size, the lower the repair cost and the higher the economic benefit.
In addition, monitoring the operation of the bearing and systematically repairing the bearing before it fails can get twice the result with half the effort. Following a reasonable process, using efficient repair equipment and tools, and obtaining the help of a professional bearing factory, all help to improve economic efficiency.
2. The benefits of cooperating with professional bearing companies.
In the business of repairing bearings, if users can obtain the cooperation of professional bearing companies, they may get the following benefits:
(1) The technical requirements of each process of repair can be clarified, and how to ensure the overall quality of the repaired bearing;
(2) Many specialized experiences of professional bearing factories can be used, which can reliably, efficiently and economically meet the technological requirements;
(3) It is possible to order molds from professional bearing companies for use in repair operations, which may be more economical and save a lot of trouble;
(4) You can order accessories such as cages, rolling elements, rivets, etc. from professional bearing companies, which may make the repair work simple, convenient and economical.
