A bush 1 for journalling a shaft 3 in a support tube 2 has a self tapping external thread 5 whereby the bush can be screwed into the bore 12 of the tube 2 without any special measures in relation to the tube. A hexagon head collar 6 or other profiled part is provided for engagement by a driving tool. A lead-in part of the bush is unthreaded to ensure correct alignment in the bore 12. The bush can be screwed in to a precise axial position, thereby establishing the correct preload for a thrust bearing 9. |
