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

these are better then bearings on a $20 skateboard from walmart

Price cannot be beat. Not even my Chinese contact could come close to this (I could only get 10 overseas for this price). I have yet to test durability, but there are reviews of this product on that and I wont be using them in a manner that could wear them out.

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.

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.

Multiple already rusty within packaging.

Very good with them. Being used on a MPCNC.

Got these for my rollerblades and theyre just OK. Im sure there are plenty of uses for bearings that dont need to be as efficient (electric skateboard, etc.) so if you have something like that, this would be a pretty stellar deal. However, for skates and regular skateboards that you use often, you may want to look elsewhere. UPDATE: After attaching them to my skates and riding them around a little bit, they seem to have loosened up and are now gliding much more efficiently. Raising rating from 3 to 4 stars.

These bearing are cheep garbage. Fist there were only 96 in the bag. Of the 96 I did receive another 11 were missing one or both seals. Now I am down to 85. After washing them in mineral spirits to remove the toxic smelling sticky grease with dirt and other grit that was mixed in I found that I had 47 bearing where the seals fit well enough to stay in place and not interfere with the rotation. Yes I new I was ordering cheep bearings for a project with loose tolerances, light weight and low speed requirements but these are garbage. On the up side my 6 year old thinks there great.

These are 608RS bearings a good value. At first they were listed as having a nylon bearing cage but, in fact, they are steel. I contacted the seller (a small startup) and they responded immediately and corrected the description. Unlike another reviewer here, I did not find the bearings that I received to be full of grease, though. There certainly was some grease inside. If using these for light loads, like skateboarding, try opening up one side and putting a couple of drops of light oil in (I used silicone oil) and give it a few turns to thin out the lubricant a little. That really makes these spin well. If using these for heavy loads and high RPM, leave the grease in, of course, without thinning. But, if using them for light loads, thinning the lubricant may just do the trick for you.

Very rough rotation. Poor quality. Cheep but was it really worth the savings? No
