100 Pack 608-2RS Skateboard Bearing, Rolling Bearings, 8x22x7mm 608rs Bearing

Excellent delivery, great craftsmanship, performed exactly as needed!

Some of the bearing were rusted

When I first got into 3D printing, I didnt know these things existed. I quickly found, however, that the 608 is the bearing of choice for many 3D-print projects that need rotating parts. I really dont know how long it is going to take me to use all of these (so far Ive only used them in three projects), but I couldnt pass up the quantity price. They fit perfectly in every project that calls for a 608, they turn smoothly -- whats not to like.

Good bearings. Slight surface corrosion on outside but none visible under seals. Light coat of oil here and there but no evidence of intentional lubrication inside. Clean, lubricate, and inspect seals before use.

I had purchased these to use in various 3D printer guides, but they have way too much friction. Instead of rolling they just sit there as filament passes over them. I tried printing a fidget spinner as well. As I spin the spinner as fast as I can, it comes to a complete stop within a couple of second. I guess you get what you pay for.

Had five different 608 bearing types delivered to test for a device I’m building. I’m throwing these away, all 100 of them. These feel like they have sand for a lubricant, and that’s just testing with my finger tips holding and turning the bearing. Under load these will fail quickly. If you need a bearing that will only last 24 hours, this is for you.

Really good bearings for the price. Quality seems good and very smooth.

Breaks extremely quickly, unsafe for skateboarding. I bought these for backup bearings in case mine blew out at the park but even so, theyre not worth it. Theyre so cheap and fragile they get destroyed within a few hours of riding. If you want to buy these for skateboarding, I strongly recommend you dont.

These are not suitable for skating, or fidget spinners. They are full of heavy grease, and the plastic cover rubs on the inner bearings balls. The bearings are probably made for very heavy machine loads, because the ball cage is metal and double sides. Even de-greasing them and re-applying a light lubricant will not work. Maybe for other uses this bearing is OK, but definitely not OK as a skateboard bearing, which is what the product has in the title during the time of purchase and review.

First let me say I am a Forensic Engineer, next let me say that I have been in a wheelchair for almost 40 years. With that said, I have never in my life come across a product as bad as these!!!!! I purchased these less than 4 months ago and have had to replace them 4 times due to bearing failure. My application is not even a difficult one as all I am doing is putting them in the front tires of my wheelchair, yet they keep failing. They are cheap but you will spend more money replacing them than whatever you may have saved buying them. DO NOT BUY THESE UNLESS YOU WANT TO REPLACE THEM EVERY 1-2 MONTHS OR LESS.......THEY REALLY ARE THAT BAD.
