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.

Cam follower and yoke roller assemblies

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.

Self lubricating cam follower assembly

A spherical bearing has an outer ring with a concave bearing surface and an inner ring having a convex bearing surface, which is in sliding engagement with the concave bearing surface. A lubrication groove is formed in the convex bearing surface and/or the concave bearing surface. The lubrication groove is defined by a concave central portion and by convex side portions. The concave central portion has a first radius of curvature and the convex side portions have a second radius of curvature. The second radius of curvature is at least 0.7 times the first radius of curvature.
