Product Description

This 608ZZ bearing is a double shielded miniature ball bearing measuring 8x22x7. This single-row bearing is built to support radial loads and has a revolutions per minute (RPM) limit of 34,000 with greased lubrication. It is made from carbon steel for durability and resistance to deformity under heavy loads. This bearing is shielded on both sides to keep lubricant in and contaminants out. The 608ZZ bearing is suitable for use in such applications as skateboards, inline skates, and scooters and comes in a pack of eight.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

These plain and throughly pre-lubed(oh so very throughly so) permanently sealed bearings are most assuredly not what you want if you're looking for speed, however these would be perfect for that beat up old board that goes across blacktop/rough concrete/chipseal/etc that you don't want to spend a fortune on bearings just to wind up chewing them up in no time. Or maybe as a nice cheap temporary set to keep handy for just in case one of yours (or your friend's) good bearings decide to swarm.

In my case, they're also the perfect thing for my cheap wally world window a/c unit that uses these in the fan motor, with spares for future replacements. (run nearly 24/7, factory set lasted 1 year, current ones from another place 3 years & just starting to squeal on occasion. Now for the adventure of tearing the thing down again and finding out how long these will last!)

2012-03-24 update: These do not hold up well in a motor. One of the ones I put in my a/c fan motor just chewed itself up.

2013-05-17 update: Second pair doing much better than first. I had re-lubed them with thicker oil this time, which seems to have done the trick. Likely the factory lube was just too thin for the application. (higher rpms + higher heat + skateboard quality lube = bearing quickly going dry)

2014-10-06 update: a/c is dead now, too much freon has seeped out. Overall, this pack of 8 bearings was well worth it, they stretched the life of the unit several years past what it would've been originally.

Bearings arrived promptly. I am using them not for skateboards, but to build wooden toys for my grandson. It was helpful that the outside diameter of the bearing is 3/4 inch, so fits nicely into a 3/4 inch hole drilled in the wood. The inside diameter, 5/16 inch fits on a 5/16 bolt or shaft. I would purchase them again for this purpose.

Bearings came quickly and well packaged. They work very well. I Highly recommend them. I'm am using them for a camera dolly that will be in close proximity to sound recording equipment so a quite bearing was important. These bearings fit the bill.

I ordered a set of these for a woodworking project that needed a bearing which had as close to a 1/4" shaft diameter as I could find, and at 8mm, these come reasonably close. The thing that most impressed me about the bearings was that, while inexpensive, the build quality seems rather good at less than a dollar per bearing (though back when I ordered them shipping was a lot more, now they're even more of a bargain). Indeed I was contemplating spending upwards of seven dollars a bearing to get them from McMaster Carr before I found these.

The shielding around the bearing is sturdy enough to clamp between two nuts when holding it onto an all-thread shaft, and the rotation is very smooth and noiseless, if requiring more force to turn than would be true of a more expensive bearing. For my woodworking project these have served wonderfully as low-duty bearing for low-speed belt/pulley based power transfer.

I feel like most bearings out there get compared to the Bones bearings. I have not tried any others, but as a machinist I have been around bearings of different types, and these don't really stand out as exceptional. Some roll better than others. I expect a bearing to spin freely for a few seconds before stopping. Some of these do, some don't. But I didn't spend much on these. And they're cheap enough to replace whenever you want. If you have a nice board with good wheels and trucks, get better bearings. If not, then there's no reason not to get these. And if you're using these for anything else (without a ton of stress on them) they'll work fine.

Don't waste your time and money. I was trying to find some replacement bearings for a small permanent magnet motor, that had bearings that were getting noisy. These new bearings were noisier than the failed bearing. Also, they have a very poor dimension tolerance. Of the 8 bearings, some were almost tight on the shaft, and others were extremely sloppy (this is all on the same shaft).

They were not worth even trying.
