What kind of rolling bearings have repair value, and what is the best method for repair?

Rolling bearings are mass-produced mechanical parts with strict manufacturing accuracy requirements and a high degree of technical specialization. Therefore, for the vast majority of easily available bearing varieties, it should be more cost-effective to purchase than repair. Only under the following circumstances should bearing repair be considered:

(1) The failure modes of a large number of bearings of the same model used in large factories are mainly wear, fatigue or micro abrasion of the rolling surface, especially the damaged parts are mostly cages or rolling elements, while the rings or washers still have repair value;

(2) Large and extra large bearings that are on the verge of failure or have already failed without significant damage to their parts, or valuable bearings that require efforts to extend their effective service life;

(3) Some bearing varieties that are indeed difficult to purchase have to be repaired due to the lack of spare parts after failure, especially imported bearings;

(4) The bearings have minor damage, such as slight water rust generated during inventory and slight micro abrasion generated during transportation, which are easy to repair but a pity to discard.

In addition to economy, the repair of bearings also has its technicality, which requires repairers to fully understand the corresponding technical requirements of bearings, as well as the structural, technological, and material characteristics of bearings and their parts. Otherwise, it is difficult to ensure that the bearing repair has the required effect.

1、 Economic benefits of bearing repair

Generally speaking, the variety of bearings is limited, 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 benefits.

In addition, monitoring the operation of bearings and systematically repairing them before they fail can achieve twice the result with half the effort. Following reasonable processes, using efficient repair equipment and tools, and obtaining assistance from professional bearing factories all contribute to improving economic efficiency.

2、 The benefits of collaborating with professional bearing companies.

If users can obtain cooperation from professional bearing enterprises in the business of repairing bearings, they may benefit from the following:

(1) Can clarify the technical requirements for 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.
