Now this is awesome look how many bearing to get an a package what is it 20 how long is it gonna take you to go through 20 bearings in your stampede 4 x 4 well I’ve had mine for a year and I have not even used half of them they are at a great price and they will last you a good two years so do yourself a favor save some money and buy a pack

I was concerned ordering these due to the price (less than .50 cents a piece) . Some of the reviews mention some of the 20 have missing seals, etc. All 20 of mine came in sealed on both sides. Seals looked seated fine. I checked the smoothness of each and every bearing, and all 20 of them felt smooth and rolled just fine. 20 out of 20 were flawless, and now reside in my new project Tamiya Son Of Wild Willy. (Vintage Wild Willy body mounted on 4x4 GF01 chassis.UPDATE: I just received a 2nd order of these bearings. 5 star still holds. Still NO idea why some had issues, because after checking the 2nd st of 20 bearings, still all 20 had seals intact and seated property, and every one of them rolled smoothly. I did however see a mark on one of the outer races that looks like it was used, or at least installed into something at one time. But, it still looked and rolled good. Maybe it is one out of so many that they test with? Not sure, but out of a total of 40 bearings I received, 100% function as they should, no cosmetic issues with that one small exception mentioned. Can not go wrong with these, especially .45 cents a bearing.

Bearings were a great value. Worked fine. The description said blue dust shields. What I got was what was pictured. So the description is WRONG.

I don't remember. I think they work fine for whatever I used them for!

I used these in a custom right-angle gearbox for ROV. Max input speed is 16,500 RPM and these bearings show no issues so far.To meet operational requirements, my gearbox housing, shafts and gears are all made of plastic (3D printed). My shafts are 5.05mm diameter and the housing bores for friction fit of bearings on OD, is 10.95mm and these fit well. I'm sure you will find that metal shafts measuring exactly 5mm will be loose in the ID and you would not rely upon a friction fit but use some epoxy to secure them.So far they do not generate enough heat to effect the plastic housing or shafts. There has been no slipping or breakage at 16,500 RPM. I am very happy with these bearings and their value to performance.

Better then going to the hobby shop and paying 2 to 3 bucks a bearing and they last just as long

Fast and cheap, but not the best quality. Bearings are dirty, some are rusty, and some are missing a seal.
