Lortone says in their ads that the bearings in the LU6X-130 LU6X-130 are 'sealed for life'.  In everyones experience that have own one of these......would that be a true statement? 

Mine seems to be making a noise, not a grinding type noise, more like a dry bearing noise, not a squeal.
Maybe its just my imagination???  dunno dunno

Its quite a job to get it all apart so I will await some feedback.

sealed bearing will last a long time, the problem is who decides how long a life is. we have had sealed bearings in our units last 10 years or more and trhen some only last a few years. a lot has to do with heat and ambient conditions like dust and water. But on the whole they last a long time

Hopefully I will outlive the bearings in my saw! The seals will definately live as long as the bearings....................

I picked up one of the old slant front 8" Lortone arbbors with noisy bearings once.  I replaced with good ball bearings and noise stayed the same.  I'm guessing the thin tin hood acted like a megaphone amplifying the sound.  If the shaft doesn't move up or down or side to side you are probably alright.

This could very well be what is happening.  I just about have them out so I will take a good look (and feel) then decide what to do.  Bearings are expensive and I don't want to replace them if I don't have to.

Actually, Lortone lists bearings really cheap.  I think through Kingsley also.

They are 16.20 plus tax and shipping.  I will check with our local bearing supply house and see what they have.
Thanks for the heads up John.

Well, I pulled it all apart today and I did have one bad bearing.  It was quite rusty and was the one on the saw end rather than the grinder end.  I will probably replace them both since I have it apart.  I'll go to Columbia Bearing on Monday.
