Please help identifying a bearing

TN9 - Glass fibre reinforced PA66 cage, ball centred (does this still exist? Can't find it anywhere)
Ball centered is typical. Inner race or outer race guided are typically only found with brass cages as the cage actually rides against the races if race guided. These should only be used in oil lubricated applications.

I have no idea if these special material cages can race guided or not. Never worked with them.
Got my bearing delivered finally today! And what a coincidence, also got a reply from SKF.

Not sure why they're suggesting 6011-ZNR/C3
Z stands for shield on one side, but I'm sure the bearing I got, 6011-NR/C3 should work fine
So i guess they changed their naming convention, but good to know.
