Abstract

1533360 Bearings MOTOREN-UND TURBINEN-UNION MUNCHEN GmbH 27 May 1977 [18 June 1976] 22505/77 Heading F2A A bearing assembly for a high speed rotor R comprises an axially fixed ball bearing 2 and an axially preloaded angular contact bearing 4, the two bearings each being mounted with radial clearance around the outer ring so that during operation oil under pressure can be fed into the radial clearance spaces.
