Threaded nuts are not really the correct way to preload bearings. However I guess we all use them. The finer the thread the fine the adjustment of the preload. Also using a second nut to lock the first will usually upset the adjustment of the first and is not the best method. The nut thread and faces should be lathe cut as should the shaft thread.

Does it make a difference to use a fine thread or coarse thread? Thanks. |
