Anti sieze and oil combo?

Anti sieze and oil combo?

Anti sieze and oil combo?

(OP)
Theory:
Too much anti-sieze is added to a bearing that is bathed in oil. What happens to the oil? The machine in question had "metals" in the oil samples, high axial vibrations and the oil viscosity was reduced from 150 to 50. I believe the bearing heated up and froze as to prevent axial movement, subsequent loading forces cause the axial vibes to go up. Has anyone had a similar problem?

RE: Anti sieze and oil combo?

Chaotic,

I have had a similar problem which involved WD40 and oil-impregnated bushings.  WD40 is an anti-sieze compound and it was found to be leeching the oil out of the bushings.  The more I used the WD40, the more the parts began to stick.  Hence.. adding more WD40.  It was a visious cycle.  You need to make sure that the anti-sieze compound is approved/compatible with the oil/grease that you are using.  That's where I'd start.

Good luck.

RE: Anti sieze and oil combo?

Anti-sieze is essentially grease with zinc and/or copper power mixed in.  That may explain the "metals" in the oil samples.

RE: Anti sieze and oil combo?

anti-sieze was for bolts and nuts only, in a harsh enviroment
like a tractor duing liquid fertilizer, keeps everthing from rusting on, that was the way i was trained, we sold it to every farmer that came in to the shop back in the 70's

soulds like some one is trying to use it as a thin grease, as stated above the copper and zink do not like the heat from rotating parts

using a proper grease or oil sound safer to me
