摘要： A roller assembly includes an outer ring having an interior having an inner surface extending an overall axial length between first and a second axial ends. The inner surface has a radially inward facing bearing surface extending between first and second radially inwardly extending flanges. The roller assembly includes a one piece inner member extending into the interior and having a groove formed therein between third and a fourth axial ends. A retaining ring is positioned in the groove. A first row of first rollers is positioned in the interior and between the retaining ring and the first radially extending flange. A second row of second rollers is positioned in the interior between the retaining ring and the second radially extending flange. An annular seal engages the inner member and has an overall axial width no more than 6% of the length of the outer ring.

摘要： An expandable sleeve for an interference fastener has a hollow elongate stem extending axially between an insertion end and a head portion. The elongate stem has an inside surface and an outside surface. A portion of the stem has a fluted shape and/or has a cylindrical shape with a conical portion.

摘要： A cam follower assembly includes a shaft having a body defining a flanged head having an outer bearing surface extending therefrom. An outer ring is positioned around the shaft thereby forming an annular space there between. A plurality of rollers is positioned in the annular space. A channel extends through the shaft and branches radially outward at an outlet to communicate with the annular space. A lubrication assembly is positioned in the shaft and includes a pressurizing device located upstream of a lubrication reservoir and a metering device positioned downstream of the lubrication reservoir. The lubrication reservoir is in fluid communication with the outlet. The lubrication assembly includes a membrane positioned downstream of the lubrication reservoir. A piercing device is positioned proximate the membrane to pierce the membrane and release a lubricant from the lubrication reservoir.
