🛹 Sackorange Miniature Skateboard Bearings: Ultimate Performance with Shielded Design Review

These bearings are suitable when precision is not required. As you can see from the photos, the left one is of good quality, the right one is not very accurate at all. .15 provides a very loose fit on precision shafts. External dimensions are ok. The bearings are very sticky, but that's normal, a little alcohol won't fix that. They are a bit difficult to turn but I think that means they are well lubricated in my opinion. Hope that helps. OUT

I bought two more packs of 30 for a lot of money. These are just as good. I mainly used rollers for 3D printing. They work perfectly for this purpose. Okay, I'll wipe off the outer grease. I was concerned that I might need very little resistance for the coil rollers. But a little resistance actually helps. They are near perfect with factory lubrication. After there were too many of these, I 3D printed some spinners. They are also good for this purpose. They don't spin well with lube. If you…
