Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings（Pack of 20)

Bought these for a filiment guide i was printing. 4 stars only because they arent high end bearing but they are excellent value and come in 2 plastic tubes for storage. Must have for 3d prints

Inexpensive option for non performance related projects where the bearing must spin but does not need to spin freely/loosely (ex a carousel vs a fidget spinner). -- 100% worked for what I needed but will likely look for a different freer spinning bearing on my next purchase.

Picked this up for a spool holder and they worked great! Had to spray down with some WD-40 and roll a bit but once that was done they worked great. Have a few more filament guides Ill print that will use this but great for what they needed to do.

These are labeled as 608ZZ and are double metal shielded. The ability to spin freely is somewhat limited for some reason. I dont know if the grease inside is too thick or what, but if youre looking for a bearing for a fidget spinner then you might want to look elsewhere. On the other hand, there is no play between the inner race and the balls and outer race, so I cant say they are sloppy loose either. I think they are a god value for the cost as long as you are not wanting something that is going to spin freely for any length of time.

They come coated in thick greasy shmoo and dont spin well at all. but a few liberal sprays of WD-40, spinning it a few times in-between sprays, and they spin real nice. about 4 out of 5 spin well so far, some have what feels like metal bits in them that prevents super smooth spin. i havent taken the lid off of them, just sprayed the sides, and the WD-40 works its way inside. for 10$ getting 20 of these, even if only half worked, i would have been happy. im using these for robotics, not skateboards. packaging is a little lacking, but ive seen worse

If you have 608 bearings for guides these are great and priced right. You can replace every year for a very cheap investment.

Good bearings. I have used these in a variety of 3D printed projects. They exhibit a little more friction compared to the bearings found in fidget spinners, but they will last much longer I am sure.

Product is as described

I had to make a bass string winding machine for musical insterments and these bearings are just what I needed. In the pass bearings like these were in windmills, worleyjiggs I think its what they are called forgive my spelling! Since you cant find them in local stores you have to depend on reviews like these. YES I WILL USE THEM AGAIN. Good luck!

very good for my job
