A roller assembly includes an outer ring having an interior area defined by an inner surface extending between a first and second axial end thereof. The inner surface has a bearing surface. A flanged headed shaft having an exterior bearing surface extends into the interior area. The shaft has a circumferential retainer receiving surface thereon. Two rows of rollers are positioned in the interior area with a spacer ring therebetween. A retainer ring is secured to the retainer receiving surface. The two rows of rollers and the spacer are axially retained on the shaft by and between the flanged head and the retaining ring so that the roller assembly withstands an axial load of up to 100 percent of an applied radial load.
