Bearing snaprings

I always thought it would be cool if the core of a wheel had a groove in it for a snapring,just like the ones that hold sheilds into some of the better bearings,only bigger,maybe flatwire instead of round.

spacer

being thinking about spacers more and their effectiveness, but still many times when I run spacers and speed washers, after cranking down the nuts, there are often some resistence when free spinning the wheels.
It also seems to me that even when using a spacer in a wheel, the side load is still put on one single bearing since our bearings are not tightly fixed (sideways) in the hub. Example, on my stradas, the inner bearing can be popped out the core (sideways) quite easily.
I think Herbn mentioned something before about fixing the bearings to the hub.
Also, got some pleasure tool sealed bearings, very nice.

To Dr Dave,
There seems to be a lot of confusion about spacers, I hope this helps.
Any ball type bearings which run in pairs and are:
(1) Designed to take lateral loads. (i.e. turning, sliding)
(2) Do not have an interference fit or shoulder between the bearing inner race and the shaft. Require spacers.
Neither of these requirements are met on our skating trucks since our bearings are loose fit onto our axles. In proper bearing application there should zero relative movement between either, the inner race and the shaft, or the outer race and the bearing housing (wheel). The purpose of the spacer is to lock the inner race together to form an assembly and limit relative movement. In addition the spacer should be exactly the same length as the distance from the outer bearing seat to the other outer bearing seat. This is the same distance as the inner lip on your wheels, and can be easily measured with a set of calipers. With a proper length spacer in place one should be able to tighten the axle nut down to its proper torque (14 – 18 ft-lbs.) and have bearings spin freely. If you do not run spacers you will notice you can only tighten your axle nut so far before you begin to preload the inner races. What you are doing is squeezing the bearings together so that the balls start to bear on the sides of the race instead of the center as it is designed. This will cause poor bearing performance and premature wear. Fortunately for most longboarders (racers excepted) we do not load our bearings or use them long enough for them to generate much heat, so most people have gotten away without spacers. Not using spacers will increase your risk of wheel/bearing failure, although small, why take the chance.
Proper spacers become even more critical with ceramic bearings. Here’s why. In a steel ball bearing the loaded ball distorts similar to pushing the end of a pencil eraser against the desk. This deformation causes friction. The beauty of ceramic is it is very hard and distorts very little compared to steel. This lack of distortion results in a bearing with less friction. Unfortunately because of this lack of distortion the load per unit area is higher. Much like the damage done to your hardwood floor by a woman walking in bear feet vs spiked heels. Ceramic is very strong but is not very tough, i.e it is brittle, and susceptible to failure due to impact loading (i.e jumping/ banging). This is a major draw back of ceramic and along with its high cost keeps ceramic bearings from widespread use. Now if one does not use spacers and preloads the bearing, the combination of the higher unit load and nature of ceramic will increase the likely hood of bearing failure from an impact load.
To Adam on the use of fully sealed bearings.
I have one board I have used for over 20 years without bearing maintenance of any kind The seals not only keep out the bad stuff but they keep the good stuff in, lubricant. If you live in Seattle where it rains and the roads are sloppy then you will love fully sealed bearings.

8mm spacers

Longskate.com sells 8mm spacers, $4 for a set of 4. They are hidden in a secret spot on the website. First you click "Wheels," where you find a warning that all Gravity wheels need 8mm spacers. Then you click -- this is the secret part -- "Kryptonics."
(76mm Krypto Classics and the Route series use 8mm spacers, as do Hyper Stradas and apparently also newer Spitfire wheels, according to reports on alt.skate-board.)

I e-mailed the owner of PTC to see if the ceramics included spacers or needed them. Unfortunately, he didn't know. Can anybody comment?

I'm running these bearings on thios set-up and they are very d=fast indeed. OK so the set up is killa, but the bearings are just so fast. I paid 10 bucks a set for em plus shipping. I bought a few sets and I'm never going back to Bones.

Not only are there abec 7s very affordable, but so are there ceramics. I used them at Donner (i did clean out the gel and used my own secret sauce) and they were very competitive compared to other bearings i've run. A steal of a deal.

Gravity Wheels (Spacers?)

I just got some Gravity Street Gs at my local skate shop (Bill's Wheels in Santa Cruz), and was told that Gravity does not have ANY spacers available. Some of us actually like to set up our wheels and bearings as they are designed to be, with bearing spacers. Crazy huh?
Any whackos out there know where I can get some spacers for Street Gs? Or at least what the size they are? (looks like about 7 or 8 mm).
Thanks, Mathew

Pleasure Tool sealed bearings

On 8/24/2001 Adam

I wanted to skate these for a while before reviewing them to see if what I suspected was true: that modern sealed bearings could hold their own against the current crop of shielded bearings, and without frequent cleanings. I've been riding the Pleasure Tool ABEC 7 sealed bearings and I find them to be quiet and fast. After nearly a month of daily riding on the city streets of Oakland and SF -- with no cleaning whatsoever -- they are still quiet and fast. Did I mention these ABEC 7s cost all of $12 per set?
Go to their web site and read up on the difference between shielded and sealed bearings. I'm now a sealed bearing fan for life. And I won't miss all the fussing with solvents and lubes that go with running shielded bearings.

This is a really (possibly) inaccurate comparison using my girlfriends' twins as test pilots, butt boarding in the parking lot of her condos:) distance to stop and crossways between garages (like a mellow big halfpipe),her board has brand new(still 70mm) powerpaw orange, mine has chunked and coned red aluminators worn to about an average size of just under 65mm. They(the twins) weigh about 53 lbs.My bearings have seen maybe 40 mph this is not my go fast board,but still they are cleanly spun out, her bearings have fresh oil.My board won everytime every division,which is kind of expected,this is a low speed test,and the low inertia set up should win,well i got a new set of lummys waiting for a rematch,maybe with new ninja's, that might be a fair test.

Marcus,
Probably the biggest factor with any bearings you might use is how clean and oiled they are. A properly cleaned and oiled bearing should work just fine regardless of age.
Check the archives here in bearings for dozens of ways to clean and lube those old dogs! HR

Will having one bad bearing affect you noticably at speed? A wheel fell off sliding today and I can't find one of the bearings. Should I replace it with a new one, or will it matter if I just plug an old one in there?

I got these 2 days ago and have ridden them for 4 hours+.
First of all, these were 25$. I put them on 76mm wheels, and went down the biggest hill closest to my house. They
roll real fast, but arent as smooth as my Bones Swiss. They make a hissing noise when i spin the wheel, but keep going more than my swiss bearings.

I had some lucky abec5 that split really easily- I took out the green plastic retainer, rolled all the balls to one side, and pushed the inside race out easily by hand.

Just for fun I decided to see how hard it is to bust a bearing spacer out of an old bearing...
Peice of cake! Lock that puppy into a vise and give it a good squeeze... cracks in half, balls go flyin', spacer drops gently to the floor (wear safety glasses!) HR

Black Panthers are fairly fast and last for quite a while! They come with washers and aren't too expensive. I put them on my Lucky Speedline deck and I thought they were great! I reccomend Black Panther bearings for your skateboard.

Tom,
You are not alone, i use cheap bearings bought in bulk. when they have been in a while i pull them out of my wheels, rip a shield out, clean & oil them & use as spares

I threw a new set of these on my pool deck and found them to be excellent. Fast right out of the tin. They ran me about 26.00. I put in spacers and orings on either side of the wheel. Real fast. I heard spacers were key. Any thoughts.
