Un twist

My new super g is hard to open and and close how can I fix that

It’s probably new, that’s a good thing, it means the threading is strong! You’ll just have to break it in a bit.

ok sounds good

Just twist EXTREMELY hard to get it apart.

The middle of the bearing seat were it goes in the bearing turned silver

Because it has a tight bearing seat so when you unscrew it and screw it you scrape of the ano. It affects absolutely nothing.
