Hi, Ncrick.

That's a friction fly - it uses the barrel as a friction point as the arbor turns a friction disk. Over time, these start deteriorating as friction starts sanding down the insides of the drum, especially if the clock movement is dirty. If it is working fine and creating enough friction to reliably control the strike train, I would leave it.

I haven't worked on friction fly movements - I'm sure that other people will (no pun intended) chime in and give advice on how to clean it if need be. :)
