Seems like 5052 is not durable enough to take the load.
If IFI uses 6061 the wheel would work much better.
Since IFI produces a lot of their their aluminum products using CNC sheet metal fabrication machinery, it would not make sense to use 6061.

5052 (along with many of the 5xxx grades of aluminum) are much better suited for CNC turret/punch and bending machines than 6061, which is less malleable and more prone to cracking during cold rolling operations.

You can't do much cold bending of 6061 and hope to achieve a bend radius equal to the thickness of the material, which is possible with several different 5xxx grade aluminum up to about 0.125" thick.
