Abstract
A bearing is provided. The bearing includes: an inner race; rolling elements located in an array around the inner race; and an outer race located around the inner race and the outer race is configured to retain the rolling elements between the inner and outer races, wherein at least one of the outer race and the rollers have an external profile that is a non-circular external profile and thereby configured to exert a linear motion in a radial direction to a work piece in contact with the external profile as the bearing rotates with respect to the work piece. A method of rotating a cam is provided. The method includes: rotating a bearing about a substantially constant center; and causing rolling elements in the bearing to rotate along a non-circular and circumference line and about the substantially constant center, wherein the circumference line has high portions and low portions wherein the high portions have a longer radial distance from the substantially constant center than the low portions.
