Repair conditions and best methods of rolling bearing

 

Rolling bearings are mass-produced mechanical parts, and the manufacturing accuracy is very strict, and the degree of technical specialization is very high. Therefore, for the vast majority of bearing varieties that are easy to buy, it should be more cost-effective to buy than repair. Only under the following circumstances can the bearing repair be considered, namely:

(1) The failure forms of a large number of bearings of the same model used in large factories are mainly the wear, fatigue or fretting of rolling surfaces, especially the damaged parts are mostly cages or rolling bodies, and the rings or washers still have repair value;

(2) Large and extra-large bearings are on the verge of failure, or have failed without major damage to parts, or expensive 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) The bearing is slightly damaged, such as slight water rust during storage and slight fretting and abrasion during transportation, which is easy to repair and a pity to abandon.

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

First, the economic benefits of bearing repair

Generally speaking, there are few varieties and large quantities of bearings, 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, it can get twice the result with half the effort to monitor the operation of bearings and repair them in a planned way before they fail. Following reasonable technology, using efficient repair equipment and tools, and getting help from professional bearing factories are all helpful to improve economic benefits.

Second, the benefits of cooperation with professional bearing enterprises

In the business of repairing bearings, if users can obtain the cooperation of professional bearing enterprises, they may get the following benefits:

(1) The technical requirements of each repair process can be clearly defined, and how to ensure the overall quality of the repaired bearing,

(2) We can make use of many special experiences of professional bearing factories, which can meet the technological requirements reliably, efficiently and economically;

(3) You can order the dies with a work card quantity from professional bearing enterprises and borrow them for repair business, which may be more economical and save a lot of trouble;

(4) You can order accessories such as cages, rolling bodies and rivets from professional bearing enterprises, which may make the repair work simple, convenient and economical.
