Mega midi 6 bearings question?

[CM007]

How often do these bearings need to be oiled?

I've done it a couple of times, but I should have probably checked first.

Both bearings are sealed so adding oil will only attract dust and dirt, very lightly oil or grease of you are going to do this. Main item is to periodically clean. I just replaced one of mine a few weeks back after 2 1/2 years of running. It had a rough spot and was time to change.
