You
DO NOT need a thrust bearing. Keep the mast above the rotor as short as possible if using the 3020. (6 inches or so) Having too mast above the rotor is the real deal breaker with light duty rotors.
My 9521 lasted many years (still works, but not using it) even though I used too much mast above the rotor for over a year as seen in
this photo.
