  • Cheap, light duty, fine for what they are
Number of Items: 50
I bought these bearings for 3D printed fidget spinners, for that they are completely adequate. The tolerances are definitely less than precision. A couple of the shields (out of 50) were poorly installed. I was removing the shields on some of the bearings anyway, so it was fine. The bearings come with sticky grease (like almost any bearing) so they don't spin freely, but after a little cleaning and a drop of light oil they spin easily. I would highly recommend these for light duty projects. They're priced great for that. I wouldn't use these for anything that needed close tolerances or serious performance. I wouldn't install these anywhere they were a pain to replace, because I have doubts that they'd hold up to real abuse. ... show more

  • Sturdy, Cheap, but Sticky - They need cleaning.
Number of Items: 100
Bought the 100 pack. They came in nice little tubes. 2 boxes of 50. They're pretty good depending on your needs. The Good: These have metal retaining inserts and seem pretty stable laterally, I only measured a couple but they seem pretty dimensionally consistent as well. The Bad: Maybe they've been sitting on a shelf for a while but the whole lot was sticky to the touch, like oil that's dried up a bit. out of the box they won't spin freely for even a single rotation (see video). I hosed down a few with some bicycle chain de-greaser, rinsed them, toweled them off, then doused them with WD-40 to drive out any water. then they spin pretty well (I plan to add some silicon based lube) For my needs they're fine with the higher resistance (grease? oil?) or the cleaning overhead isn't an issue to make them low resistance. If you need these in bulk where you want to pop them in right away and need low resistance out-of-the-box I would avoid these. ... show more

  • I would buy again
Number of Items: 100
The value for money on these bearings were great. They offer nice smoothness when spinning the quality and durability are great. It was a perfect fit. I was able to use for multiple different functions. Pair as well with 3-D printed objects. The Spinability is great does not lock up.

I appreciate the quality construction of these bearings, as they have held up well under various conditions and intensive use.

  • Work great after decreasing and oiling.
Number of Items: 100
I use these on a DIY CNC plasma table gantry. They are very sticky and do not spin well at first, but if you decrease them with bicycle chain degreaser, the foaming kind, and then oil them, then they work great and spin freely. Just wish they were usable out of the box.
