PURPOSE:To eliminate the necessity for high accuracy in assembly of a bearing, by interposing a spacer, which concentrates the pressure cone apex of angular bearings, between the paired angular bearings. CONSTITUTION:A spacer 10 is interposed between a pair of angular bearings 1, 1. And the paired angular bearings 1, 1 are tightened by a step-differenced part 11, formed on a ball thread 2, and a nut 13 being screwed to the ball thread 2 and gastening inner rings 12, 14 of the bearings 1, 1. While the bearings 1, 1 are mounted by a bearing retainer 15 screwed to a bearing member 14. The spacer 10 is formed to a thickness equal to a distance (a), between pressure cone apexes of the bearings 1, 1, obtained when they are closely positioned with each other without causing the spacer to be interposed between the paired bearings 1, 1, consequently the pressure cone apexes of the bearings 1, 1 can be concentrated to one point 16. |
