The cam follower roller device comprises a body, a shaft mounted on the body, a roller mounted on the shaft and able to rotate, and a plain bearing interposed radially between the shaft and the roller. An outer surface and/or an inner surface of the plain bearing comprise a plurality of cavities. The ratio of the sum of the surfaces areas of the cavities to the total surface area of the outer surface, or of the inner surface, in which the cavities are formed is between 2% and 40%. The cavities have a depth between 0.5 &#x3bc;m and 5 &#x3bc;m.

Cam follower roller device

The cam follower roller device including a body, a shaft mounted on the body, a roller mounted on the shaft in a rotationally movable manner, and at least one friction element mounted on the shaft axially between the roller and the body. The friction element is separate from the body and from the roller.

A roller bearing comprises an inner ring, an outer ring and an annular cage. The annular cage retains and guides at least one roller body. The annular cage comprises at least one pocket for retaining the roller body and at least one retaining rim disposed on one axial end of the pocket. The retaining rim extends at least in the radial direction relative to a main body of the cage.
