I don't understand why it mentions a PF30 BB
Because it's just a set of top hat bushes to fit the 24/22mm GXP axle into 30mm ID bearings. It will work if you have 30mm ID bearings installed in an 86mm wide shell.

What do you mean by this? I have a GXP crankset and bb386 frame with no bb.

You need a set of bearings as well as those adapter bushes in order to get your GXP cranks to work in your 386EVO shell.
