All of this info is something to bearing mind 💩

Highlights - Buy cheapest bearings - apecs doesn't matter - Shielding: Get 2RS. (double rubber sealing > Z, which is metal) - Material: The harder the better. #1 is ceramic, #2 Ceramic hybrid - Maintenance: Grease > Oil (I.g. WD40), Grease: Slower, long lasting Oil: Quicker, needs replacement Bonus: if you can hear the bearing, it's dry. Time to grease

Wow. The first 10 seconds of this video answered the question I have had for the past 3 hrs haha. Thanks!

This is just the best video I have seen on the explanation on Abec. Love that you give those engineering insights and gotta say I laughed out at the calculation for abec 1 which was 377 km/h, very well explained. Thank you!

Omg I have to buy most of my gear online and the amount of time I wish I could just walking into a store like this 😍 and that's just the wheels and frames I can see!

Great info! Thanks for making this video.

THANKS! Finally a simple, straight forward explanation of a not so simple question! Can’t wait to see your other videos.

I'm grateful to find this video. Thank you for sharing your expertise and and insight! 💫

Thank you for posting this, I'm glad I watched the whole thing

Very informative and well explained. I really like that you added technical information too. Thank you!

Good job guy!!! One of the best and most complete explanation you can find on KZfaq about bearings!!! My compliments !!!! 👍👍

Watching this in 2023! This video was very informative. Thanks for sharing, buddy! Jst got my new pair of inline skates and needed to learn more about bearings - Cheers! (Frm Malaysia)

Thank you so much for the information! Also, love the periodic checks to find the right English word. Adorable! 🥰

Very good..simple, direct...no high tech speak.

Thank you so much for this video! You're easy to understand and I love you comparison to the streak! Ha Ha! Im getting back into quad skating after 37 years and NOW I know all about bearings! Subscribed! Thanks!!

I love the the song, it's "feel good" music! Also, the info was just what I needed

Thank you Ivo, this is precisely what I needed to know about bearings!!! They are now no longer a mystery. And I love your humor … but you knew that already. Looking forward to your next video so I can get more informed about all things skating - and laugh out loud at the same time. See you soon so you can pimp my skates with new wheels, cuffs and other stuff (and, yes, also cheap bearings) - always great service in your shop.

You are such a good and honest dude. I miss Holland so much.

Ivo, je bent nu officieel mijn held. Now i know i don't have to spend 50 bucks for one set of new bearings! 💪🏻

Thank you for tis in-depth explanation!

Thanks for sharing the valuable information. It's very helpful.

That's nice from a mechanical view; those inserts were insightful from an industry point. The conversion of rpm into kmh demonstrated well for enginneering (as I tried calculation too for labels really depicting it.) This video suited me well with much more engineering and mathematical backgrounds than just a couple of years as "fresh" start into skating. Thanks.

Great instructional video!

thanks for opening my eyes.

Outstanding explanation.

I always tell people buy basically the second cheapest thing you can find. The very very cheapest is likely to be factory seconds and may have defects and grinding dust in them from the factory. But yeah, as you said, the cheapest bearings that aren't complete crap will work equally well as the most expensive ones.

Thanks for good information about bearings..

best bearing explanation ever ... and funny .. i was ready for a ver necessary but boring lesson... but this was well done ! btw the bagettes .. "cylinders". :)

Excellent video. I was seeing a competition among parents to purchase bearings for their kids, and was in two minds on what to do.I am now better informed to decide.

TIL! thanks for this well detailed explanation!

I never knew this. Thanks, great info. That graph is awesome.

Great video. Very informative.

wooow. thank you so much for this video. Very well explained, it was easy to understand! Loved it.

Damn, honesty? I haven't heard that in a while, thanks man!

Super informative, Thanks Ivo!

Fantastic video!! I've learned a lot about bearings in the last few years thanks to cycling and channels like Hambini, but this is a great, decently concise breakdown for the purposes of skaters. I would note that ceramics are pretty much useless for us; hybrid ceramics will simply wear a groove in the steel races, and full ceramics are ludicrously expensive, crack, and are even faked with plastics. Much better of with quality steel from a trusted supplier. Also, with how exposed skate bearings are, i often like to use a nice thick grease in them as opposed to a less viscous drip lubricant - they do feel slower out the door but they soon warm up on the roll and provide far better protection if i'm skating in shitty weather, meaning less fussing over maintenance. now, for manufacturing tolerances in the skate industry in general....

Fantastic video thank you

I used ABEC5 my whole skateboarder's life and they are absolutely fine. Also pretty fantastic little things. I've heard they heat the rings so the balls fit then the bearing is fully operational when reaching more normal temps as the rings shrink and wrap the balls so they cannot escape. I've also heard "A country's technological level could be measured by the tolerance in the bearings it produces" BTW: As a skateboarder I didn't care and used WD40 but with inline skates I pretty much prefer silent bearings that go smooth, so grease is definitely my choice, and I'm somewhat generous. Grese is THE number 1 bearing choice and also the choice to make it silent. I have a fan, one day I cleaned the bearing then applied WD40. It was horrible, then I applied a very viscous grease (lots of it) and it made it absolutely silent.

fantastic video! loved to watch you translate as you go -that made me subscribe!

Fantastic, informative video!!

finally a fellow engineer whos into skates EDIT: ben je godverdomme ook nog eens nederlands

Can I add this video to my skating page. This is hands down the best bearing info and explanation I have received in my 4 years of skating.

You are great! Finally a man who tell the truth🤙

Best explanation out there!

Fantastic explanation 😊

Great job. Awesome video 😊

really good info mate. thank you for the video

What a great video Thank you!

thank you for that intro xD still watched the whole vid!

Een goede uitleg lekker praktisch daar hou ik van.

Great detailed info. Thank you. Good classic country song too.

Great video show informative, thank you.😊

Thank you efo, your videos brought me back to the shred gang 🛼🛼❤🙏🤙

Great info Ivo 🎥! Besides bearing shields & seals, we find that a Labyrinth seal (stepped inner race + rubber seal) is even better at keeping dirt out.

DUDE thank you I needed this I love to skate and have been servicing my skates for a while but never knew what the ZZ Z RS and all that junk mate Great Job!

that was fun... :) i actually learnt something.. thank you

Great video!

Very good information 👍🙂👍

It’s so sad that every day it’s becoming much difficult to find good videos like this one. Thanks a lot for you time.

Maybe it doesn't matter if you buy from a reputable skate shop but you can not say a quality bearing brand has the same properties as a cheap Chinese bearing that have really bad plated mild steel and the quality bearing has chrome steel. Really informative content thanks for sharing.

Loved it, great work again Ivo, I am kinda weird (you already know that) but I actually like to maintain my bearings

I have bones swiss ceramic bearings, I'm had the bearings in my cruiser boards for over 10 years and they are still perfect and I ride everyday.

this was so helpful thanks :)

Thanks for the information I had no idea I just thought most expensive is best

The one thing not considered in this video as far as the impact of new bearings vs. old is that almost every time you put new bearings in, you are putting them into NEW WHEELS at the same time. People tell me all the time, "I got new wheels and bearings, and they are so fast now!" It's the WHEEL. My lap tests with the same wheel model but comparing new to 3-5mm worn down wheels is usually about 15 seconds per mile (10 sec per km) while using the same bearings in both. As for maintenance, I skate in the rain fairly often (including getting caught in a storm last night) and my current method is to turn a space heater fan on low heat and stand the skates up in a V to dry them out, then flip the V around to hit the other side. Then I put the skates back on and roll. If any wheel is still stuck after that, or not rolling smoothly and freely like the others, I hit it with WD40. Like he says, it just isn't worth the time and expense to go through cleaning every time I get wet, and it's not important enough to only skate when I know it is 100% not going to rain. Eventually, the rust degrades the races and the bearing loses sideways tolerances and starts to be a problem. At that point, I start thinking of switching them out, since they get close to rubbing the wheel against the frame.

Excellent!

Good stuff 😃

Wow! You gave so much information. Very good video. I definitely learned quite a bit. Thank you so much. I will go check out the wheel video, now... +1 subscriber :)

Thanks for sharing

Best of the best man

I've used the Wicked bearings for a while now and they seem to maintain their speed really well.

Things I got from this, you want smooth balls, the harder the better, grease is better for lubing up. Thank you! I asked a lady at a skateshop what she uses and she showed me some bionic bearings, I ended up getting them, they were very middle of the road in pricing. This because I bought some light up wheels because my inner child wanted them but straight out the box they had no roll to them, I tried some 3 in 1 oil but it didn't help, I switched out the bearings and now they roll free

New skater here...I thought it was a fitting size...like if my quad wheels have ABEC 3 in them then I would always have to buy ABEC 3...and I couldn't find them online...so I can buy ABEC 1 to 9 and they will always fit my new wheels...thank you so much!!!

Big THANKS !!!!

Very informative thanks, it says “page not found” when clicking the beating cleaning article in the description though…

Good video

THANKS A BUNCH!

Thanks!

Very cool instructional video with lots of background info. It’s cool to to hear this from somebody who’s actually studied this stuff. I’m just wondering: what letters are used to indicate bearings that have metal shields, but that can be removed and put back in using the small circular piece of metal running along the inside of the outer ring of the bearing?

Oust bearings are the only bearings that have been specifically redesigned for the unique forces placed on them during skating and skateboarding, that is to say, axial and torsional forces in addition to radial force. Best skateboarding bearings available are the Oust MOC 9 Air Bearings.

Hey folks - NEVER EVER use WD40, as it is not a lubricant, it is a "Water Dispenser". It is something that actually strips the lubricant from your bearings. Much like Acetone or Isopropyl Alcohol does, when you use it to clean the bearings. Always use grease or oil.

So I could use a skateboard bearing on rollerskates?

When using oil, how often should you maintain your bearings? After every session or once a week or month?

tks for video. 1 question ABEC X ILQ?

...great video - makes a lot of sense. I miss the Netherlands and the straight-talking Dutch.

do new bearings need be broken in?? Some say yes, because new grease is thick. Thank you.

If you have the time, hope you can do a video on the sounds bearings make and when is a good time to replace them. The spinning the wheel part can help a little, but doesn’t solve the problem of my wheels making funny noises while skating. Some noises go away after around 5 mins of skating (I have many pairs of skates). The contact area (say the bearings and the bolt or the spacer) can make these noises? I tried to lube the bolt but the noise doesn’t go away. Could the bolt be bent?

Cheers😎

Great video man. A bit too technical but really enjoyed it! The only thing I would have liked to get some explanation is the difference between steel and ceramic bearings. You passed by it like it means nothing and some in depth analysis would be nice.

Ik heb ooit zealous lagers gekocht voor mn longboard. Kan ik ze ook voor mn fitnessskates gebruiken?

What if the bearings are sealed on one side and has plastic ball retainer (the ones that looks like crowns) on the other side? Do you have to remove the retainer to clean the bearings?

You are wrong about bearings. It’s too bad the inaccuracy of the Abec rating system has muddied the waters. However, bearing quality does matter, especially in a roller rink situation, where bearing loading can be much more than your body weight. The cheaper steel ball bearings will heat up and slow you down. Ease of roll is lost. It matters most for adults, who weigh more than 180 lbs. Ceramic bearings are best for heavier skaters. It’s worth the extra money and will roll smoother for longer. Bones Swiss Ceramic. There is none better for quad skating. I have skated the same set for 15 years. Still the best bearing I ever skated.

I’ve always struggled with understanding one thing and you seem to know that 😅 So what happens to bearings while putting them into wheels and then into a frame? I can’t get rid of feeling that they’re much slower after assembly.

Its called tolerance in the US also.

If you know where to get 608 bearings 2RS or ZZ with DLC, then get then and they might be endless if you clean and libe them. Problem is that they are usually sold in enterprise batches.

What bearings do you recommend for skating in the rain or wet conditions? Thanks!

Hi there could you please help I’ve brought some abex 11 are they good to go or should I put oil on them ? First

Hi,I'm writng from Kazakhstan and I havn't found liquid lubricants for abec - 9,can you advice what type of oil can I use that easy to find(somthing like motor oil)?

What is the standards size of inline skates bearings? There's something I'm trying to make, and I need the smallest size available..

The same conclusion applies to bicycle parts. Really fancy bearings might save a fraction of a watt. Dirty/dry/broken bearing waste a meaningful handful of watts.
