ABSTRACT:
A spindle motor using an hemispherical-type air bearing, wherein air circulation means is formed on the shaft inserted and fixed in the air bearing, so that air inflow to the air bearing and air circulation within the bearing are highly facilitated, whereby friction and wear phenomena between the hemispherical balls and the ball casing is reduced and noises are inhibited, and whereby the life span of the air bearing can be extended and the performance of the spindle motor itself can be enhanced.
