ABSTRACT:
A radial bearing comprising a cylindrical bearing member and a shaft arranged therein, the member and the shaft being rotatable with respect to each other and one of the cooperating bearing surfaces of the member and the shaft being provided with a pattern of shallow lubricant-pumping grooves which, during relative rotation between the member and the shaft, build up a pressure in a lubricant present between the shaft and the member. In one axial zone of the member or the shaft the relevant bearing surface is provided along one half of its circumference with a groove pattern which is arranged to pump in one circumferential direction, and along the other half of its circumference with an identical groove pattern which is arranged to pump in the opposite circumferential direction.
