YAMASO20 Pcs 608 2RS Ball Bearings – Bearing Steel and Double Rubber Sealed Miniature Deep Groove Ball Bearings (8mm x 22mm x 7mm)

I bought these to use in a filament respooler design I found online. They were exactly perfect for that use. They were all dimensionally near perfect and have enclosed bearings. They spin freely. My use is low force, so I can’t comment on how long they might last in loaded use.I’d buy again.

I am using these in a filament drybox (3D printing); these are perfect and a good price for this application. They come in a metal tin and are adequately oiled. They spin smoothly but not fast like a high-end skateboard bearing.... perfect for my use. i have bought 3 sets so far with no problems.

They seem well machined, and well lubricated. I built a lazy susan with them, and it works great. I don't know much about ball bearings, but these seem fantastic.

They worked fairly well, they didn’t grind or have any odd behavior. They were packaged nicely in a metal tin that was put in a bag, the only problem with it was they where hard to get out of the tin and hard to put back in too (at least without denting the tin) they where a little greasy/oily on the outside, but other than that the bearings themselves where fine, i didn’t hear any grinding either. They fit with the 3D prints I made fairly well and I assume they would fit well with other things too, the seal seemed fine and you can remove them to re-lubreacte them if you need I think

Husband was pleased with size, quality and durability. Can’t remember which project he used these for but they worked as they should! Said it was great price point and quick shipping. Likes how smooth they are!

they glide quite well. but you need 8 mm rod of a fairly good precision to use them for rotary projects. someone noted that they were able to create a lazy Susan with then too. your imagination is tge only limit with these gems. no noticeable grease leakage. you get about 16-20 i think for the price listed. i havent had an application that tests the tolerances or load capabilities yet but they are quite sturdy in their design.

My original order was lost in transit by USPS and never arrived. However, the replacement arrived in a timely manner. I purchased this set to add a bearing to a 3D print. The bearing fits the standard 608 size hole I printed and rotates smoothly.

Good product and good price
