A roller assembly includes two outer rings rotatably mounted on a shaft by a respective set of rollers positioned between the shaft and each of the respective one of the outer rings. The shaft has a head flange on one end thereof and a groove formed therein at a distance from the head flange. A retainer ring is positioned in the groove and another retainer ring is secured to the shaft at a distance from the groove. The retaining ring is configured to space the two outer rings apart from one another so that the two outer rings are operable and rotatable independent from one another.

Cam follower with multiple rows of independently operating bearings

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.
