ABSTRACT:
The disclosure concerns an anti-friction bearing between a rotating shaft and an external bushing. The bearing includes two axially spaced apart rows of bearing balls. A feed bushing is disposed in the space between the shaft and the external bushing and between the two rows of bearings. The feed bushing is open at the axial ends for dispensing lubricant to the rows of bearings at the axial ends of the feed bushing. The feed bushing holds lubricant, such as grease, in itself for being dispensed at the axial ends of the feed bushing. A porous elastic material may be disposed in the feed bushing for being impregnated with the lubricant. The feed bushing, and also the porous material if used, are elastic and resilient to permit deflection of the shaft with respect to the external bushing. Various shape and configuration feed bushings are disclosed. A lubricant recharging hole passes through the external bushing and communicates to the feed bushing.
