In our daily work, how to determine the bearing is not possible to continue to use in our work must become familiar with the problem, here we have the first choice, and we briefly explain the four points of SKF bearings:
    (1) SKF bearing rings and the circumferential surface should be well supported even by force, in order to reduce distortion, and give full play to the carrying capacity of SKF bearings.
    (2) in their mating rings can not slide in the tangential direction of the surface, otherwise it will damage the mating surfaces.
    (3) the free end of SKF bearings must be able to change the length of the shaft and the bearing bore SKF adapt, that must have the ability to adapt to the axial position of swimming within a certain range.
(4) must pay attention to the SKF bearing installation and removal easy, saving time saving time and labor costs.
Comply with the above four points good reason chose SKF bearings, but the bearings during operation there will be some damage, as the staff how to identify problems in time to seize the opportunity, and to report to the relevant department or the relevant bearing repair company to reduce further damage and economic losses?
SKF bearings repair have certain principles and methods, Bearing Co., Ltd. for everyone here a brief look.
 1, to determine the best time to repair the bearings
Rolling state to work to repair what is better, which to judge from the damage patterns and characteristics of SKF bearings. Use the most amount of damage to small and medium sized bearings, usually fatigue and excessive wear rings or rolling elements based. When SKF bearing rolling surface into the third stage wear, or pitting and spalling, the SKF bearings will soon become invalid, then the destruction of SKF bearing raceway surface has very serious, very difficult to repair, or Repair lose value.
But SKF bearings before said stage, relatively minor wear and fatigue may occur only in the depth of the lower surface of the rolling surface layer several microns to tens of microns, and therefore at this time machine SKF bearing repair, you can use a small price get a better repair effect. In summary, the repair of SKF bearings to when the bearing has worked for a long period of time, has been fully utilized, but before the damage is repaired enter the most appropriate.
2, bearing repair method for determining the timing of the report
SKF Bearing whether judgment should be concrete repair method, which has been bearing the full use of and destroy approaching specific determination method appears as follows:
when a) the use of bearing working condition monitoring equipment bearing operating state judgment and decisions should be bearing repair, which is the most convenient and more reliable method.
For example, when using the HD-1 type instrument, when the pointer approaching the danger zone from the warning area, and in the improved lubrication and other measures taken did not return a pointer, it can ascertain the Swedish SKF Bearings own problems, then you can take advantage of yet entered When the danger zone, the bearing repair. Exactly how far away from the danger zone begin to repair, by experience adjustments. With such equipment, can take advantage of the bearing potential, bearing repair promptly and avoid failure, it is safe and economical.
b) the use of simple tools to monitor
In no case have the above instrument, the operator can hand-held tools such as rod or wrench conflict closest to the bearing shell machine parts, listening ear ashamed by the tool came SKF bearings operating sound tool. SKF Bearing normal operating sound should be uniform, smooth sound without harsh without the normal operation of the bearing, there are a variety of intermittent sound, impact or harsh sound.
