Asymetrical new roller wheels

Hi all,

This is a bit special. I bought roller wheels for an industrial application requiring to open and close a kind of door/drawer mounted on wheels (there are 5 wheels at the top and 5 wheels at the bottom).

However, I have noticed that the wheels I just received are slightly asymetrical (see picture). The right side is more rounded than the left side.

Is this something common? What are the consequences? Will it get worn out faster?

The wheels will be mounted vertically (without angle, as it may be under roller wheels).

Thanks a lot in advance
