Hi Lester,

Ballscrews can take a surprising amount of dirt. I have seen quite a few
commercial routers with only very basic wipers on the nut to keep out
the big bits. Dust doesn't seem to do much harm. Admittedly most of them
do pump grease directly into the nut which will tend to push the dust
out. I know of one that works hard 5 days a week and the nut only sees
grease when I get called in to fix a fault on the machine. Most of the
time it runs bone dry.
