BEARING RING OR THE LIKE WITH SET SCREW ABSTRACT OF THE DISCLOSURE The invention contemplates an improved set-screw shaft mounting for a machine element such as the inner race ring of an antifriction bearing. Tolerances are closely controlled for both the set-screw threads and the tapped-hole threads, for the case of set-screw threads which are yieldable in the context of an interference (i.e., friction-fit) to the tapped hole, the interference being such as to occasion a friction torque which is but a small fraction of the conven- tional maximum comfortable torque of wrench appli- cation by a machinist, using a conventional wrench, such as an Allen wrench. The low friction torque enables the machinist to know precisely when the set screw intercepts the shaft into which it is driven, and he can then know that his manually applied maximum torque will be serving essentially only the intended purpose of clamping to the shaft. Extended running life is realized for bearings thus mounted, as compared to conventional set-screw clamping.
