Rolling bearing repair conditions and the best repair methods.

Rolling bearings are mass produced mechanical parts, and the manufacturing accuracy is very strict, the degree of technical specialization is very high, so for the vast majority of bearings that are easy to buy, it should be more cost-effective to buy than to repair, only in the following circumstances, to consider the repair of bearings:

(1) The failure forms of a large number of bearings of the same type used by large factories are mainly wear, fatigue or freting abrasion on the rolling surface, especially the damaged parts are mostly cages or rolling bodies, and the rings or washers are still worth repairing;

(2) large and extra large bearings, on the edge of failure or has failed and there is no significant damage to the parts, or valuable bearings must try to extend their effective service life;

(3) some bearing varieties that are really difficult to buy have to be repaired without spare parts after failure, especially imported bearings;

(4) minor damage to bearings, such as slight water rust during inventory period and slight fretting and abrasion during transportation, is easy to repair and unfortunately abandoned.

In addition to the economy, the repair of bearings and its technical, which requires that the repairman fully understand the corresponding technical requirements of bearings, and the characteristics of bearings and their parts in the structure, process and material, otherwise it is difficult to ensure that the bearing repair has the required effect.

In general, the variety of bearings is small, the number is large, the price of a single bearing is high, or the structure of bearings is simple.The larger the size, the lower the cost of repair, the higher the economic benefit.In addition, the operation of the bearing is monitored and the FAG bearing is repaired in a planned way before failure, which can get twice the result with half the effort.Adhering to a reasonable process, using efficient repair equipment and tools, and obtaining the help of a professional bearing factory can all contribute to economic efficiency.
