A thrust bearing assembly includes a single-piece thrust plate and thrust shaft flange having a generally cylindrical body portion, a frustoconical body portion and a bore extending through the cylindrical body portion and the frustoconical body portion. The bore defines a first bore section and a second bore section. A lip extends between the first and second bore sections. The first bore section, the second bore section and the lip are configured to receive a thrust shaft and axial thrust forces transmitted therefrom. The thrust bearing assembly also includes a bearing assembly in operable communication with the single-piece thrust plate and thrust shaft flange. The bearing assembly supports rotation of the thrust shaft and includes a plurality of first rolling elements. The bearing assembly includes a bearing cage to retain the first rolling elements and a plurality of second rolling elements disposed between the bearing cage and the thrust shaft.

Combination thrust flange and thrust plate

A rotating combination thrust plate and thrust shaft flange (), and a thrust bearing assembly () incorporating the rotating flange plate combination (), in which the rotating flange plate combination () has a generally cylindrical body portion () which has a rotating base surface () and a lateral surface (), a frustoconical body portion () which has a frustoconical surface (), and a bore () extending through the cylindrical and frustoconical body portions (and) and having a first bore section () and a second bore section () wherein the second bore section () is adjacent the rotating base surface () and has a smaller diameter then the first bore section (). The first and second bore sections meet at a junction () defining a lip () which is designed to support a complimentary lip () of a bore shaft () thereby restricting the movement of the bore shaft () in the direction of thrust in an extruder.
