I had to give up my old cast iron table saw, my favorite power too,  and buy a contractors saw. This was caused by my new location and lack of space. I can easily move this saw on wheels anywhere. I bought a nice Sears model about 4 years ago and it actually does a good job for what it is.  I have 2 complaints, one that it is under powered. Secondly the bed is plastic and the sliding miter is bushed into place with plastic spacers riding on aluminum. After a while they must be adjusted or as was the case this time, I dropped it. Anyway with all the problems that go when you align your saw guides and miters, you don't want to have the parts wear much, and you don't want to do it any more than you have to.  So now the question. ( didn't think I was going to get to it, did you?)

What lubricant do you use for moving table saw surfaces that are plastic on aluminum?, such as the slides on my miter. 

Johnson's paste furniture/floor wax.

plastic on aluminum?

Maybe a PTFE spray. 

Wax is cheap and can't hurt anything.

No silicone. That'll destroy your project finishing efforts and  possibly destroy the plastic. Some polymers develop crazing and cracks when exposed to silicone

 While we use a silicone spray at work to make plastic parts slide off better, it also has a problem of gumming things up.  Our's is a "Mold Release" in a can.   Any wax or even a lithium type grease will attract dust, then it is time to clean the gunk out.   maybe a Powdered Graphite type  for the tracks.

Better yet, can you ditch the plastic parts and go with metal?

Graphite will get on the wood. so will lithium grease or any silicon grease.

Johnson paste wax or butcher block wax is good.

That being said, Beosheild is the stuff your looking for.  Costs more but the stuff is incredible. Use it on the top too.

Spray on, wipe down your good to go.

 Thanks guys. I worked at aligning the sliding bed, miter gauge and fence for over an hour. Checking and rechecking as I went. I actually had this job in mind as a routine job preparation, but I dropped the sliding bed and the miter on the cement floor. It really wacked things. I always have Johnson's paste wax on hand and applied it to the moving surfaces. It is as smooth as a baby's butt and cuts as square as possible. 

 While I was at it I cleaned and lubed the worm gears underneath with graphite spray. It instantly dries and leaves a very slick surface. Even better than new. I'm happy now. :-)
