The vibration assembly also includes a cage positioned between the vibration race and the additional race and rollers positionable in the cage, the rollers rollably engageable with the non-planar engagement surface and the another engagement surface to vary the distance between the vibration race and the additional race whereby axial movement is provided in the downhole tool.
