weird pulley noise

[Qking95]

I did the tension pulley delete cause I kept hearing a noise from the belt area. So I figured that was it. It ran good for 200 miles now at an idle one the pulleys being the PS, A/C, or main crank puley makes kinda like a metal on metal sound it's hard to describe but any thought would be great please.

A bearing may be on its way out. My alternator made a metal-on-metal grinding noise that got progressively worse when the bearing began to fail.
