Abstract

PURPOSE:To prevent skuffing by conducting air, absorbed from an inflow port provided on a center housing and made in high presser through balance channels, into a pneumatic bearing chamber. CONSTITUTION:Balance channels 9 are provided on positions moved by same angles from the position P2 which is the position of symmetry with respect to the position P1 on which a pneumatic bearing chamber 40 on inner periphery surface of a center housing 22 receives maximum pressure. Outer air absorbed from an inflow port 71 is made in high pressure through the balance channels 9 and the same makes pneumatic bearing loading ability in contact zone of the pneumatic bearing chamber 40 increase. Thereby, scuffing can be prevented.
