Nice product. Machined and surface finished nicely. Rolls smoothly around the axis. No crunchies as they say. I actually bought more for my project they were so nice. Hopefully this is a good supply going forwards.

There nice.Super smooth and heavy duty.Used them for an anchor system on a drift boat that I’m building

they work very good I am very well pleased with them.

Our zip line OEM bearings were so cheap that they were worn out after less than three months of very light use. These units made our line faster and smoother than new. Haven’t had them long enough to report on longevity.

Bought these to replace one I had that wore down. These worked great so far. The kids have only used the zip line a few times since Ive replaced it with these so time will tell us on the longevity.

These are the best I can find. I wish they were cheaper but quality sometimes costs.

Work just as expected and timely delivery!

The bearings seem to be of good quality and should work well for our intended purposes.
