This question might be too simplistic for FineWoodworking, but I figured it couldn’t hurt to ask.
In building my shop (part time shop- part time garage) I made some built-in cabinets (like every guy does, right?) and in one of the cabinets is a full extension slide out tray for my miter saw.
This worked great for a couple of days, until the ball bearings got coated with sawdust. Now, instead of a slide out tray, I have a tug out tray.
Does anybody have a better idea ?
Thank you,
John

You need to run a branch from your dust collection system to each slide.
No, that's stupid...but you could try taking out the slides and de-grease them before replacing the grease with a lube that does not capture and hold dust. Perhaps a silicon or graphite based product?
Ok. I have some graphite spray, so I can try that.
What do you recommend for de-greasing ?
OK, they are sliding well now. I cleaned out the oily sawdust from the ball bearings with a mineral oil bath and lubricated them with graphite and silicone sprays. So far so good, but I have yet to give it the sawdust challenge though.
Dispense with the roller bearing slides and make some wood on wood slides. FWW issue 143 shows how to make some that work quite well and should be able to tolerate the dusty conditions you have. I have made several sets for my shop.
I would agree with bilyo. Plain old wood on wood slides are probably the best in the shop. There's nothing to get gummed up with sawdust. They are easy to make and fit and a bit of hard paraffin every few years will keep them sliding nicely.
