I would like to know more about fluting failure on electric motors bearings.

I have a little information regarding this issue like the use of special bearings; is there any site or literature when I might review?

Thanks in advance

Regards

I have one or two articles about this subject
Mr.Cornelio may contact me.My e-mail address<thomas_purackal@pic.com.kw>

Estimado Jesús, in general, please be careful to take the advertising about special bearings without a full understanding of the subject. The bearings can be for instance insulated with a thin layer of nonconductive material. It is still a capacitor and conducts high frequencies well. There are several steps to undertake before you must also take the relatively high cost of special bearings and they rarely help alone. Read Thomas´ texts and if you need more, just drop a line. arne.lindholm@bluebottle.com

Do a Google search on electrical fluting...there is loads of info on the subject. Also, I found two articles particularly useful. The first is a product technical paper, but has some good explanation of the issue and possible solutions.

The other is simply a diagnostic help.
