Imported bearings have strict requirements for manufacturing accuracy and a high level of technical specialization. Therefore, for the vast majority of easily available imported bearings, purchasing them is more cost-effective than repairing them. Only under the following circumstances should the repair of imported bearings be considered.
(1) The imported bearings used in ball mills mainly fail due to wear, fatigue or micro abrasion of the rolling surface, especially damaged parts such as retainers or rolling elements, while the rings or washers still have repair value;
(2) Imported bearings are on the brink of failure or have failed without significant damage to the parts, or valuable imported bearings must find ways to extend their effective service life;
(3) Imported bearings have slight damage, such as slight water rust generated during inventory period and slight micro abrasion generated during transportation, which are easy to repair but a pity to discard.
The repair of imported bearings should not only consider their economic benefits, but also technical factors. Repairers should fully understand the technical requirements of imported bearings, as well as the structural, technological, and material characteristics of imported bearings and their components. Otherwise, it is difficult to ensure that the repair of imported bearings meets the required results.
It is best to cooperate with professional import bearing enterprises when repairing imported bearings for ball mills, because: (1) it can clarify the technical requirements of each repair process and how to ensure the overall quality of the repaired bearings; (2) Many specialized experiences from professional bearing factories can be utilized to reliably, efficiently, and economically meet process requirements; (3) You can order work card quantity molds from professional bearing companies and borrow them for repair business, which may be more economical and save a lot of trouble; (4) You can order accessories such as retainers, rolling elements, rivets, etc. from professional bearing companies, which may make repair work simple, convenient, and economical.
In addition, in daily production, it is important to monitor the operation of bearings and carry out planned repairs before bearing failure, which can achieve twice the result with half the effort. At the same time, following reasonable processes, using efficient repair equipment and tools, and obtaining assistance from professional bearing factories can all help improve the economic efficiency of enterprises.
