Patio door rollers don't roll freely

I ordered 2 rollers number 81-158 on 9/25/2017. After installing them the door did not roll much easier than the old rusted rollers except they didn't occasonally 'catch'. I thought after some use they would brake-in and would be easier to open the door. This did not happen and now that is is colder it is even harder to open the door. Is this normal for this roller? I replaced the rollers on a different sliding door using roller assenbly 81-156 back in March and it opens very easily. I have adjusted the door up a little bit and cannot find anything causing the door to be hard to open. I removed the roller assemblies and the the wheels on the assemblies do not turn easily. Any suggestions to remedy this problem would be greatly appreciated.

That solved the problem. The door opens and closes easily now.
