Call the parts store. They will be able to tell you if the pulley is available separately or not.
A bearing used in a pulley is typically referred to as a "pulley bearing" or "sleeve bearing." These bearings facilitate smooth rotation and reduce friction between the pulley and its shaft. In some applications, ball bearings may also be used to enhance performance and durability.
ALL harmonic balancers for ALL American car engines (and all other vehicle engines that I know of) are in the same place. They're integral to the front engine pulley that drives the serpentine belt or fan-belt, whichever your engine has. Yours has a serpentine belt.

The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
