Best linear bearing system for a dusty router

[ddgman2001]

What would be the best linear bearing system for wood routers regardless of cost?

My machine uses V-wheels and track which work OK, but need frequent cleaning.

I can see the recirculating ball style gumming up with sawdust pretty quickly.

I've heard good things about the Frelon one piece bearings in dusty conditions.

Look at the industrial CNC routers costing over $100,000. They almost all use THK linear bearings. They use a wiper to clear the rail of dust. You can get something similar for your Vee rollers.

it is possible to eliminate most of the dust by installing accordion tipe guards
if you go to the thk site or any company selling linear guides you can find covers tha wil cover the all thing.
the only problem is that you might loose some of the travel

And they cost a fortune. $20-$25/ft

i wrapped pipe cleaners around the rail i use the frelon slides and it works fine

I heard of a system where there is an air jet attached to the bearings and constantly blows the dust off.
