608ZZ 8 x 22 x 7 mm Deep Groove Ball Bearing, 10 Pcs Double Metal Shielded, Fit for Skateboard Bearings, 3D Printer RepRap Wheel, Longboard, Roller Skates, Inline Skates, Scooters etc. (Pack of 10)

Bearings are great for the price. They come packed in wax grease which is standard for most heavy equipment originating from China whether it be a vice or a milling machine. This wax grease must be removed before use with either a solvent or degreaser. You’ll have a bad experience like in some of the reviews if you do not. After they have been properly cleaned they can be lubricated for use. They are not same quality as a SKF but they are not 3 bucks a bearing either. I use them for 3d printing and they work great for me once they are prepared.

I needed some bearings to make a spool holder for my Ender 3 and these fit the bill. They had a pretty thick waxy coating when they first arrived. After soaking them in Goo Gone and adding a little bit of lubricant they spin pretty nicely now.Not sure how they compare the more expensive brands or how durable they are, but they've been working great for my more limited purpose.

good product. Fit exactly how I needed

They're bearings, they spin, I'm not using them for any heavy applications but hey they work. A little stuff at first but if you only need a few and want them shipped quick can't beat them.

I'm using these in some projects that need a durable and reliable bearing. These are holding up very well. No problems.Size is spot on and they are quiet in use.Given how cheap they are and how sturdy they are - I'll be buying from this vendor again.

I had a bearing in my one of my wheels on my Drive rollator.. If I got one from the company, a new wheel is $25 plus ship..So instead I bought these bearings. It took me about 10 mins to replace both bearings in that one wheel and five mins of that was rounding up my tools for the job..As a retired Machine Repairman I know bearings pretty good and I will say that these Bearings seem ok.They have no burrs and they are smooth rolling. At the price and for what I am using these for (low speed - light pressure), I didn't need the best bearings made -- I think these'll be fine. If not I have 8 more to put in..

Important preface: I am using these bearings for 3D printed projects. If I were to use them for skateboarding or vehicles, the results may not be 5 star for those purposes. So far the bearings have only been in use for less than two months, but they have been great.

These are the stickiest bearings I've ever seen. 0 glide, gross to handle, sticky as hell. They fit the application, so the bearings are definitely correctly sized. They do turn, and I'm sure they're fine for any application with real weight, but if you're looking for bearings that will keep spinning after turning, the ones I received wouldn't work.Maybe it's my fault, maybe idk dick about bearings and they're supposed to be filled with peanut butter. Either way, they didn't work for me.
