Ball Bearing vs. Journal Bearing

Journal bearing center cartridges cost less than ball bearing units of the same frame size while still delivering the airflow this platform is built for. If outright spool-up and response are the top priority, the TNT5R Ball Bearing lineup offers faster response in the same sizes.
