<P>PROBLEM TO BE SOLVED: To suppress inaccuracy in assembly height of a thrust cylindrical roller bearing. <P>SOLUTION: Raceways 3, 4 of both bearing bases 1, 2 are formed to have a convex shape on a radial plane, cylindrical rollers incorporated into the bearing comprise two or more classification groups different in roller diameter tolerance, respective cylindrical rollers in the groups are placed in three or more circumferentially equally-spaced positions different for each group, and the bearing is operated only when the raceways 3, 4 remain in the convex shape and all the cylindrical rollers are supported by top parts TP1, TP2 of the convex shapes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
