    • Excellent value
Size: 625 Style: 625
I don't expect a lot from cheap Chinese ball bearings, but these surprised me. Not a lot of play in the bearing. The OD measured 15.995mm and was round within 0.001 mm. It's difficult to measure the ID, but it might be a bit small, perhaps 5.99 - not sure however. Be sure to understand the difference between RR and ZZ bearings. These are RR or rubber sealed so they are protected from the outside environment. This is because the rubber seal actually touches the inside race. ZZ bearings have metal shields, but there's a tiny gap between the shield and the inside race so not as well protected. The advantage of ZZ is they can run at higher speed and have less friction. ... show more

    • If you need something to spin at a gentle touch, this isn't it.
Size: 608RS Style: 608RS
More friction than I was expecting -- would have liked something a bit smoother and isn't great for things that need light touches, but it worked for what I bought it for -- good enough..

    • These are ok bearings
Size: 608RS Style: 608RS
The bearings are fine for their stated use. I personally think the lubricant they use is way to thick for the purpose of the bearings, but then again I'm not the manufacturer. If the grease it to thick, you can wash it our and replace it with a lubricant that works better for your application. My biggest gripe about these bearings was the way that they were shipped. I bought a multi-pack (20 pieces) and the box of bearings was thrown in a box with other items. During shipping, the box they were packaged in opened and several of the bearings actually fell out of the outer shipping box. Amazon made good on the order and replaced it, but it would have been smarter to secure the bearing package before tossing it in the shipping box. When all was said and done, these bearings are decent for the price paid and I'm able to use them for the purpose I purchased them for. ... show more
