If you mean the accessory belt lhs AC tensioner pulley, about 180,000klm on my car, replaced with new for about $60 from Makin & Luby. Or pull one from a wreck or press a new bearing in if you are smarter

Replace belts when cracked or worn. Or maybe every 100,000 klm, details in the FSM id imagine...
