Hello, I have a Proxxon IB/E Professional, but the bearing in front of the machine has no protection from dust partices that eventually kills the bearing.
I replace my second time and they last 4 to 6 months.

To make the problem worse the bearing is very hard to replace, for an idea see here: Tweaking a Proxxon IB/E mini drilling machine - Blogs and ...

So my question is how can I solve this other than mount some sort of dust sucking machine ?
