Claims18
A torque converter comprising:
- a cover;
- an input shaft supported for rotation within the cover;
- a bearing coaxially-aligned with a portion of the input shaft;
- a hub surrounding the input shaft;
- and
- a seal element interposed between the input shaft and the hub;
- wherein the bearing includes a seal retaining flange adapted to cooperate with the hub to define a seal groove in which the seal element is retained.

A bearing comprising:
- an inner race;
- an outer race;
- and
- a plurality of rolling elements supported between the inner and outer races;
- wherein the outer race includes a seal retaining flange extending radially inwardly beyond the inner race for retaining an associated seal element supported on a shaft;
- wherein the seal retaining flange further includes an axially-extending flange extending from the radially-inwardly extending flange;
- wherein the axially-extending flange includes an inner circumferential surface adapted to engage the associated seal element and an axial end face adapted to engage the associated seal element.
