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

Yup, they are bearings. But would not give above a C rating for condition, even at this price. Packing was lacking. All just in a big bag. I found at least 3 different labels on the seals so thinking its a mixed batch of brands. Probably why some seem ok and some not so much. Also cleanliness control was lacking somewhere. as several of them have heavy grit all over. Normally would not care that much, but considering the seal is questionable on many of them as well, its likely the grit got into some. Wanted to use out of the bag, not have to clean and re-lube before use. One seal was missing a part altogether, and others have gap where you can see the bearing inside. Would have been just as well to get non-sealed bearings.

You get what you pay for. I realize these are only ABEC 1 rated. But, wow are they sloppy. the 8mm hole has a decent amount of variation. turned a shaft to fit the 1st bearing perfectly, the next wouldnt go on, and the next was loose.Once a shaft is fitted to the hole, ALL i tested (gave up after about 20) have more wable than Id expect. IE, spin it on a fixed shaft, and the outside casing doesnt spin even close to true with the inner casing. Some were pushing almost 1/6th inch.

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.

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 bearings are not the greatest. I purchased them for use as a piece of a filament dispenser for a 3D printer. Basically, snap into place and spin. Thats all they had to do. The bearings felt oily yet werent actually very well lubricated inside at all. They also smell noxious, as contrasted with the ones I ended up buying after these, which spin immaculately and have only a subtle and inoffensive scent. Soaking these bad boys in Mineral Spirits did not help. The inside diameter is also wrong. Its like half a millimeter too large. This might be fine if all youre doing is making mediocre fidget spinners, but for use in an application where you expect to pop these onto something, they will be loose. Worth it to spend the same price for half the number of bearings from a decent seller, especially if you only need a few.

So I opened the a contaner, each one has a set of ten. First thing I noticed is the seals looked odd. So I pop one out, they are plastic, not rubber of any kind. Thereis very very little grease inside, could be a good thing or bad depending on your use. My intened use is for a bearing to last so I need grease inside. So I check 10 more same thing. That takes me to the biggest problem. These called seals you can see the balls inside with the seals in place from the factory. No way will they seal in the grease or keep dirt out.

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.

Very smooth rolling. Capable of use with heavy load

The price is really the only reason they earned 4 stars. The quality and function varied wildly within the batch; some of the stamped steel bearing cages were deformed to the point of being almost completely locked up. However, they werent too greasy or messy and all of them were dimensionally correct. They came with a heavier grease in the bearings, more fit for doing work than hitting maximum RPM. I needed about 60 of these for my project and had to trouble coming up with that many acceptable pieces out of the hundred, so Im satisfied.

Did not fit as expected, fits sloppily on the axle what about a half a millimeter of Clarence although this may have been partially my fault but
