The harmonic balancer consists of a pulley, bonded to a vibration-damping element (rubber or similar), which is then bonded onto the hub that's pressed on the crank.
Over time, it's not uncommon for the inner element or bond to deteriorate, separating the pulley from the hub slightly, and often causing the pulley to wobble (the crank and balancer hub still spin true).
The stock balancer is notorious for this. Rare to hear of it occurring on aftermarket balancers, but still not impossible.
