Well, I would guess a pulley is being made in a two step process (CNC mill, then anodize), but if you want a rubber insert, it would be made in a lot more steps, as two pieces of aluminium need to be made, then a piece of rubber needs to be made, and sandwiched between the aluminium. All these extra steps would need more time, and a lot more labor, and as a result, a lot more money
