Abstract

1462233 Bearings VYZKUMNY USTAV BAVLNARSKY 22 Oct 1974 [24 Oct 1973] 45748/74 Heading F2A [Also in Division D1] An air bearing comprises a hollow pin 9 supporting a shaft 12 and an air pressure line 13. An air cushion is formed in clearance 91 during use. One hollow shaft 12 is fixed directly to the rotor 140 of an electric motor 12. (For Figure see next column.)
