A cam follower roller assembly has a shaft insertable into a roller. The shaft has a zerk in communication with the channel wherein lubricant can be added to the assembly. The design of the assembly in one embodiment is such that a larger shoulder to shaft radius stabilizes the shaft and limits the shaft from rocking or elongating within a mounting hole. When utilized in the application of a loading mechanism and carriage assembly for trash collection vehicles, one embodiment of the cam follower roller assembly provides greater life and easier serviceability.

A mechanical system that forms a cam follower or a rocker arm. The mechanical system includes a support element, a pin extending between two opposite ends along a first axis, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element further comprises an insert having holding members supporting the pin ends, provided with cut-outs having a shape complementary to the shape of the pin-ends, for assembling pin with insert by quarter-turn around the first axis. The pin ends each have a flat surface and an external surface. A first dimension of each pin end, measured perpendicularly to the flat surface, between the flat surface and the external surface of the pin end, is higher than half the outer diameter of the pin ends.

A cam follower assembly for a can bodymaker includes a slider structured to be coupled to the proximal end of a ram body of the can bodymaker; and a plurality of cam follower members rotatably coupled to the slider. The cam follower members are structured to be operatively coupled to a cam of a ram drive assembly.

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 μm and 5 μm.

A linear actuator for driving an actuating member of an internal combustion engine of a motor vehicle, the linear actuator having two rolling bearings for scanning mutually opposing sides of a rib that is formed as a guide curve. The rib has a variable width, against which the two sensing bodies are biased to reduce or eliminate undesired reaction forces.

A cam follower roller device, notably for fuel injection pump of an internal combustion engine, the cam follower roller device comprising a casing, a shaft mounted on the casing and a roller rotatably mounted on the shaft. The casing comprises on its periphery at least four openings made through the thickness of the casing and located in such a way that two openings face one end of the outer cylindrical surface of the roller.
