A roller assembly (10) 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 (13F1,13F2). The roller assembly includes a one piece inner member (14) extending into the interior and having a groove (15) formed therein between third and a fourth axial ends. A retaining ring (16) 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; second row of second rollers is positioned in the interior between the retaining ring and the second radially extending flange. Wherein a ratio of the roller length (LI) to the roller outside diameter (Dl) is less than 2.8; the outer ring (12) having a second outside diameter (D); wherein a ratio of the second outside diameter (D) to the roller outside diameter (Dl) ranges from 7.25 to 9.75. An annular seal engages the inner member and has an overall axial width no more than 6% of the length of the outer ring.
