The roller gates in Dam No. 21 were designed to submerge to a depth of 4.67 feet, but engineers were still dissatisfied. In 1936, the Corps designed roller gates for Dam No. 22 that submerged 8 feet. In this design, the engineers also incorporated a Poiree dam trestle the same height as the downstream fender on the adjoining piers.

The advantage of this design is that the tapered rollers have a positive alignment with the shaft. That is, each roller will align itself perfectly on the tapered faces of the cup (outer race) and cone (inner race). In addition to tapered roller bearings, there are a number of other roller bearing types including cylindrical and needle bearings ...
