A cam follower includes a shaft and a hub rotatable with respect to the shaft via at least one bearing. A flanged tire is affixed to the outer peripheral surface of the hub, the flanged tire having a main body portion and a flange portion extending radially outwardly therefrom. The main body portion and the flange portion are integrally formed from a polymeric material, and the hub, the main body portion and the flange portion are disposed so as to define a generally planar outer surface. A flange support plate, having a support plate outer diameter that is generally equal to or greater than the flange diameter, is positioned abutting the generally planar outer surface and is rigidly affixed to the hub, the flange support plate being formed from a metal material, thereby providing structural support to the flange portion for axial forces applied to the flange portion.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

A cam follower assembly is provided including an improved lubricant flowpath. The assembly includes a generally cylindrical housing including an annular groove adapted to be in communication with a lubricant gallery in an engine block or cylinder head. An axial end of the housing includes skirt portions including openings, and one of the skirt portions includes a first recessed section indented from an outer lateral surface of the housing and extending axially between the annular groove and a respective one of the openings. A pin is mounted in the openings of the skirt portions and has a second recessed section indented from an outer lateral surface of the pin that extends to at least one of the ends of the pin. The second recessed section is in communication with the first recessed section, and a cam roller supported on the pin.

A rocker arm includes a roller, a support shaft coaxially mounted in the roller, walls arranged along a rotation axis and having the roller therebetween and having through holes, respectively, through which end portions of the support shaft are inserted, and each of the walls having an inner surface opposite the roller, and holding members mounted in the respective walls. The holding member includes a tubular portion mounted in each through hole and disposed between an inner peripheral surface of the through hole and an outer surface of an end portion of the support shaft, a first stopper portion included at a first end of the tubular portion to be in contact with the inner surface of one of the walls, and a second stopper portion included at a second end of the tubular portion to be in contact with an end surface of one of the end portions.

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 mechanical system, comprising a support element, a pin extending along a first axis and comprising two opposite ends, each adapted to be fitted in the support element for radial retention of the pin relative to the first axis, and a roller element movable in rotation relative to the pin around the first axis. The mechanical system includes two ribs resting on either side of the ends for axial retention of the pin along the first axis. The mechanical system can be integrated into either an injection pump or a valve actuator.

A rocker arm includes an outer arm having a first side and a second side, an inner arm positioned between the first side and the second side of the outer arm, a pivot axle pivotally coupling the inner arm to the outer arm at a first end of the inner arm and a first end of the outer arm, and a latch pin having a first position and a second position. The latch pin in the first position pivotally fixes the inner arm to the outer arm at a second end of each of the inner arm and a second end of the outer arm, and in the second position allows the inner arm and the outer arm to pivot independently. Two lost motion springs are respectively secured to mounts provided on the outer arm.

The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.
