<P>PROBLEM TO BE SOLVED: To provide a bearing device for supporting a body of a printing machine, capable of stably setting an appropriate pre-load and of improving bearing accuracy and assembling performance. <P>SOLUTION: The bearing device 20 for supporting the body of the printing machine is provided with a bearing housing 21 in which a flange part 21a corresponding to an outer ring spacer 6 is formed integrally by one member in the inner peripheral part; two outer rings 1 having raceway surfaces 1a on the inner diameter faces and fitted into the bearing housing 21 by shrinkage fitting etc. so as to sandwich the flange part 21a; two inner rings 2 having raceway surfaces 2a on the outer diameter faces; and a plurality of rolling elements 3 arranged so as to be rolled between the respective raceway surfaces 2a of the two inner rings 2 and the respective raceway surfaces 1a of the two outer rings 1 fitted into the bearing housing 21. The respective raceway surfaces 1a of the two outer rings 1 are processed after the two outer rings 1 are fitted into the bearing housing 21. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
