SOLUTION: The static pressure gas bearing supporting the rotor comprises the radial bearing pad 3 supporting the rotor in a radial direction, a linear guide 1c moving the radial bearing pad 3, and a ball stud 4 rockingly uniting the radial bearing pad 3 to a linear guide 1c. A direction in which the linear guide 1c moves the radial bearing pad 3 intersects with a direction in which the rotation center of the rotor and the ball stud 4 are united. In regard to a change amount of a bearing clearance between the outer peripheral surface 2c of the rotor and the radial bearing pad 3, a movement adjusting amount for moving the radial bearing pad 3 by the linear guide 1c is large, so that a minute amount of the bearing clearance can be accurately adjusted.

摘要： PURPOSE: To reduce weight of a spindle by forming a member to form an outside diameter wall of a bearing part out of a nonmetallic material having small specific gravity, and forming a female screw part of a fixing part of the other bearing part out of a metallic material CONSTITUTION: In a static pressure air bearing spindle, a housing 23' to form an outside diameter wall of a first bearing part X and a housing 25' to form an outside diameter wall of a second bearing part Y, are formed of a nonmetallic material such as ceramics, synthetic resin and graphite having specific gravity smaller than a metallic material. According to this, a metallic annular member 1 having a female screw la is fixed to an outside diameter of the housing 23'. Since the female screw 1a of this fixing part 3 is arranged on the metallic annular member 1, the housing 23' and the housing 25' are formed of a nonmetallic material, and even when weight of the bearing parts is reduced, there is no fear of damage of a female screw 1a part.
