Abstract: A roller bearing assembly for both radial and axial loads comprises an annular series of hollow roller bearings within associated inner and outer annular bearing races. Each race has an integral end flange which projects generally radially toward the opposite race and which defines an axially inwardly facing parti-circular annular thrust surface. The flanges are arranged at axially opposite diagonal locations so that the thrust surfaces diagonally oppose each other in the axial direction. The roller bearings have parti-circular rim surfaces which engage the thrust surfaces and with the bearings preloaded both radially and axially enhanced stiffness and running accuracy is achieved. In a second form, annular recesses provide opposite end flanges on the roller bearings with enhanced axial flexibility. Bearing assemblies may be employed in axially adjacent pairs in machine tool spindles and the like.

Abstract: The invention contemplates a removable-seal configuration for an axial end of an antifriction bearing wherein seal components are fixedly held by the outer bearing ring and position a seal ring in yieldable circumferentially continuous wiping contact with a seal surface on the inner bearing ring. The component seal parts comprise a stiff annular backing ring, and a stiff removable split ring, with a yieldable annular seal ring compressed between the stiff rings and having the wiping contact with the inner ring. The outer ring has a shouldered groove to retain the component seal parts, the groove having a section of continuously curving contour and being characterized by a convergent ramp with which a similarly sloped bevel of the split ring has wedging contact to derive the indicated compression of the yieldable seal ring.

Abstract: The invention contemplates a locking-ring configuration for use with a set-screw anchored collar, bearing ring or the like, to apply continuous load to the set-screw region (a) for enhanced set-screw clamping action upon a shaft and (b) for enhanced retention of set-screw adjustment. Various forms are described in the context of set-screw clamping of an anti-friction bearing via the inner ring thereof.

Abstract: The invention contemplates selectively securing a bearing ring or the like to a cylindrical shaft, using a collar rotatably carried on a slotted end of the bearing ring. The collar bore and the collar-overlapped part of the slotted end have substantially conforming contours; in the case of the ring contour, a minimum radial extent characterizes the angular region of any slot, and a maximum radial extent characterizes an angularly offset location which, for the case of a two-slot ring, involves maximum radial extent angularly intermediate the slots. Various forms are described.
