Abstract
In an apparatus for fabricating a fluid bearing having a dynamic-pressure-generating track slot installed in the internal diametric surface of a sleeve, a ball-escape-preventing device is coupled with a rotary shaft being in contact with one end thereof so as to form the identical outer diametric surface with that of the rotary shaft to support the ball. Therefore, it is not necessary to control the angular velocity and axial transfer velocity of a guide bushing or ring with respect to those of the rotary shaft. Also, a fluid bearing of a high precision and high efficiency can be fabricated with an inexpensive and simple device by which ball wear due to rolling can be reduced and the ball is easily replaced when worn.
