normal to need clutch adj after a few months on new one?

this is mechanical clutch, RAM B&B btw - have adjusted clutch fork rod - not exp. w/air gap adjustment - can you describe how that's done?
I adjusted my clutch just by pedal free play. The throw out bearing was constantly riding on the pressure plate fingers and the bearing failed and ruined the pressure plate. When you adjust the linkage you either close or open the gap between the bearing and the fingers. There should be a gap but not too much. Pedal free play will be correct regardless.
