Do you have your tonearm cables grounded to the phono stage or floating? Also do you have a ground wire for the bearing? You can try grounding that to the same ground. This should eliminate potential difference which leads to static.
If your bearing doesn't have a ground wire, you can experiment but taping a piece of wire at its end, with electrical tape, to the bottom of the bearing. Then connect this wire to the same ground as your tonearm wire ground. This will be non-permanent but it'll let you test whether that helps.
