Abstract: A bearing assembly for a cam follower assembly for a ram assembly for a metal can production necker includes two or more bearings. Each of the bearing includes an inner ring positioned within an outer ring and a plurality of rolling elements positioned therebetween. The bearing assembly includes a tire press fit on the outer rings of the bearings. The tire has an elongate body portion that extends between a first radially inward projecting shoulder and a second radially inward projecting shoulder. A radially inward facing surface extends between the first radially inward projecting shoulder and the second radially inward projecting shoulder. The first radially inward projecting shoulder extends further radially inward than the second radially inward projecting shoulder.

Abstract: A cam follower for a ram assembly. The cam follower includes a bearing positioned on a shaft. The bearing includes an outer ring having an exterior surface and an inner ring coaxially disposed in the outer ring. A plurality of rolling elements is disposed between the outer ring and the inner ring. A tire manufactured from a composite material is positioned on the exterior surface.

Abstract: An extended life ball transfer unit has a housing with a well of generally cup-shaped configuration with at least the lower portion of its surface being defined by a pair of radii mutually offset to opposite sides from its vertical axis to generate a gothic church arch cross section. A passage extends therethrough at the base of the housing well. Sealed in the well is a spherical conveyor ball having a radius of smaller length than the radii defining the lower surface of the well, and the well defining radii having their origins above the center of the conveyor ball. A multiplicity of spherical bearing balls is disposed between the conveyor ball and at least the lower portion of the well. The bearing balls support the conveyor ball and transferring the load from the conveyor ball to the housing over an annular area defined by an arc of about 5-15° with its center spaced about 30°–40° upwardly from the passage.
