These are really nice quality for the price. The bearing is smooth and well made. I can't quite tell what the plastic material is made of but it seems to be durable enough for repetitive movement. I'll update with any observations/changes.That said, below is my use case in the event it's helpful for others.My wife bought an old Stamina 55-4290 Pilates Performer machine. Looks to be about 25 years old, which is probably why the rubber wheel covers started breaking off.I took some measurements and these have proved to be a perfect replacement, with some changes described below.The main thing is the original wheels are part of an assembly that includes an integrated spacer. The bolts and nuts are detachable so you can reuse them for these wheels, but you need a spacer to provide the right offset so the bolts are tight and the wheels align in the track properly. Do not use these wheels without a spacer.Here's what I did. I used the existing nuts as the spacers, and luckily I had a set of matching nylon lock nuts, I believe M8 or somewhere around there. You don't necessarily need lock nuts, standard nuts should work just fine but if you want some extra security just add another nut to the end and they will lock against each other.To replace the wheels you have to loosen the folding foot mechanism, fold it in half and that allows access to the track. Detach the elastic bands from the sliding seat, and remove it. Then simply make the aforementioned changes. All I used was a box wrench for the nuts and a large Phillips for the bolt.

Bought to replace seat rollers on Tunturi R215 rowing machine and are a good fit. Good quality product. Was unable to buy original part and these are an excellent alternative at a fraction of the price.
