For conventional bearing systems, there are sleeve, one-ball one sleeve (or, ball-sleeve), and two-ball bearing systems. Fans using sleeve bearing system is the cheapest option among the three. Two-ball bearing system is, on the other hand, the most expensive. You may directly link the bearing system with the service life of a fan. Generally, the life of two-ball bearing system is longer than ball-sleeve, and ball-sleeve is longer than sleeve.
