Rolling bearings is the mass production of mechanical parts, and manufacturing precision is very strict, and a high degree of technical specialization, therefore bearing varieties most readily available, should be more cost-effective to buy than repair, only under the following circumstances before considering bearing fix the problem, namely:

(1) large factories use the same type of bearing failure is mainly rolling surface wear, fatigue or micro-abrasion, especially damaged parts still mostly cage or rolling elements, and rings or washers repair value;

(2) large and extra large bearings, to the brink of failure, or failure Although and parts no significant damage, or precious bearings must try to extend its useful life;sealed bearings

(3) some really difficult to buy into the bearing varieties, failure spare parts had to repair, especially imported bearings;

(4) bearing a slight injury, such as inventory produced during the mild water rust, as well as minor fretting abrasion during transport, such cases repair and wasteful to discard.china ball bearing

In addition to the economy, bearing repair, as well as its technical, which requires repairer fully understand bearing the corresponding technical requirements in structural bearings and parts thereof, process and material characteristics, it would be difficult to ensure that the bearing repair desirable effect.
