1)      the use of bearing working condition monitoring equipment

Spectrometer or the use of SPM, such as iron or I-ID-1 bearing working condition monitoring equipment to determine the bearing operating condition and repair should be decided when the bearing, this is the most convenient and more reliable method.

For example, using the HD-1-type apparatus, when the pointer is near the danger zone by the warning area, and in taking measures to improve lubrication of the pointer does not return, they can ascertain the bearing itself, then you can not enter the danger zone while when the bearing repair. How far away from the danger zone started to repair, the experience can be adjusted.

Use of such instruments, can take advantage of the work bearing potential, bearing repair promptly, and avoid failure, is a safe and economical.

2) the use of simple tools to monitor

In these occasion instruments do not have, the operator can tools such as hand-held rod or wrench conflict area closest to the bearing housing of the machine, the tool will be listening ear ashamed of bearing operation by the tool came the sound, of course, can also be modified using the medical stethoscope.

The normal operation of the sound should be uniform bearing, smooth sound without harsh without the normal operation of the bearing, there are a variety of intermittent sound, impact or harsh sound.
