Zealous Bearings have been some of the most popular bearing in the last few years. High quality bearings with built-in spacers and double rubber seals; what more could you ask for?

Well, what about ceramics?

Zealous now offers ceramic bearings for your speed and racing needs!

Lighter, stronger, and smoother than metal ball bearings, they're are also very corrosive resistant.

We love zealous bearings because they are high quality bearing that won't break the bank, and will keep you riding longer and faster.

Throw on a set of Zealous Ceramic bearings on your setup and you'll see what we're talking about!

Zealous's Description

Ceramic Balls
-Ceramic balls are lighter, stiffer, smoother and naturally corrosion resistant. This means we can use a lower viscosity lubricant which makes them fast right out of the tube.
Precision 8mm axle holes
.4045″ built in spacers
.5mm built in speedrings
Strengthened Nylon Ball Retainers
White rubber seals to keep dirt and debris on the outside of the bearing.
Lubed with Custom Nanoceramic Grease
-The unique feature of our lubricant is how the nanoceramic compound fills in deformations or asperities in the bearing. These deformations cause friction and heat around them which hardens the nano-ceramic compound to that specific area. This micro coating is 5 times the hardness of the host alloy and has a molecular bond with the host metal, filling in all the asperities and eliminating friction over time.
-The coefficient of friction is the lowest in the field of Tribology at 0.003% creating a near frictionless surface. Mainly because the nanoceramic compound eliminates all asperities.
-Corrosion on the inside of the bearing is nearly eliminated.
Sold in sets of 8 bearings.

Got the ceramics and they are a bit tough but I still haven’t broken them in. They coast well right out the box.

These came pretty gooped up like other reviews said but nothing s paper towel couldn't handle after the first ride. Takes breaking in for acceleration but these things fly out the gate once your cruising.

Fantastic. It’s Not Just Hype.

I was somewhat hesitant to get two sets of these considering that they’re very inexpensive for a ceramic bearing. But I decided to try them out because they have double shields, come heavily greased, have the built-in spacer/ring design, and are ceramics. That sounded to me like a really solid combination and the modest price sealed the deal. After a couple hours of riding on my new pintail (a Landyachtz Totem), I really have to say these are impressive. They got better and better through the afternoon and I’m anxious to see how they hold up to the stock Bear Spaceballs I rode all last year. Those saw around 200 hours of cruising and moderate hills with zero maintenance. The Bears were pretty much shot after that, they’d gotten really loose and loud even after a cleaning. No rust or anything like that, they just got worn and loosened up which lead to loud noises and not the best performance. I’m gonna test these Zealous Ceramics out this year in the same way and I’ll report back here in the fall with the results.

I have these setup on my maestro for commuting and these have been a blast paired with 73mm speedvents

Don't let the price fool you. These are great bearings. They ride smooth out the gate and from what I have read get better after a few weeks of avid riding. I am super impressed with them and the price.

First time trying out ceramic bearings.
on 2020-09-13 Verified Purchase
Great pricing on ceramics bearings, need a break-in time since these have a grease like substance in them, they roll nice and smooth also they are quiet. The closet bearings I can compare these to is my Bones SS6 bearings, can't say about longevity yet need more than 14 years to go to catch up to my Bones SS6 haha.

I purchased these for my wife's board, she likes them a lot. We go boarding daily and one of my boards has a set of Zealous steel bearings. She likes how she gets extra long glides.
Lots o' lube great bearings
on 2020-07-06 Verified Purchase
Leaky at first but smooth af after a few rides. You can just wipe the wheels down after a ride or two and you should be set. You'll be pushing way less with these in the board. Huge upgrade over the stock bearings in my old Arbor deck.
Perfect intro into Ceramic
on 2020-06-26 Verified Purchase
Great introduction into riding on ceramic bearings. Priced right and inline with steel bearing sets. These have been an absolute dream to ride on. Smooth and quiet ride. Takes less pushing to travel the same distance vs steel bearings, which saves energy (us old folks wear out quicker). I did not find them to be over greased as many other reviews I read mentioned, nor did I have any issues with fit (honestly though, I read all the details and sh#$ from both the bearings and wheels perspective to be certain). Popped right in to my 85mm Caguma's and I couldn't be happier.
Awesome bearings

Bought those bearings for my new Orangatang Caguama 85mm wheels for Boosted Stealth and the ride is absolutely smooth! Would definitely recommend them for anyone who wants to replace their bearings on any Boosted Board
Best Bearings Ive Had
on 2020-05-07 Verified Purchase
Honestly my favorite bearings Ive skated in 15+ years. Super smooth, super fast. Big upgrade from what I had before. Only complaint is they leaked a lot the first few days (Ive had them for a couple weeks). Doesn't seem to be affecting the ride though but man they lubed the sh*t out of these! Highly recommend still.
Super Smooth and Quiet
on 2020-04-21 Verified Purchase
These bearings have great shields. They're super quiet. They do need a little time to get started, but that's all good. It's $30 for some amazing ceramics, and Zealous has had an amazing price point for so long. If you're looking to upgrade to some 9.5/10 quality parts, get these. Oh yeah, and they're super durable.

So much more quiet than steel bearings. Super smooth too. A little slow until they break in.

Super smooth
on 2019-06-20 Verified Purchase
I usually ride bones reds and supers. These are the smoothest bearings I've used yet. If you're looking to upgrade, but don't want to break the bank, check these bearings out. They do have a break in period, and are very heavily lubed. On your first few rides, some of the lube will leak out of the bearings. Don't let it freak you out. It's better to have too much than too little. From the price point, to the built in spacers, these bearings get a well deserved 5 stars.

They’re a bit leaky like the other reviews say but honestly they ride amazing so I don't care. I ride freestyle so I’ll update if they bust but so far they’ve been holding up from me doing flip tricks and such. They ride kind of slow until you break them in, but are literally the best bearings imo once you do. Haven’t broken them in on my board yet but my friend has and his roll much longer than my metal bearings on my other longboard
Super saucy and buttery
on 2019-05-02 Verified Purchase
Bearings are really greasy out of the tube and leaked a little, but they're super smooth and buttery! I like the white color versus the original green, added some spice to my board. Even though they were greasy, they were already outperforming my Bones Reds! Can't wait for them to be fully broken in
noticeably faster
on 2019-04-25 Verified Purchase
right out of the box they were 20-30% faster than another set of builtins I had. Having put about 30 miles on them so far, it doesn't seem like they're leaking excessively like some of the other reviews seem to suggest. normal dirt accumulation. Definitely increased wheel speed, can't wait to see what they're like broken in
Hands Down Best!

Absolutely love these bearings... quiet, smooth, fast, and low maintenance. Have them in two boards now and cant stand my boards that have anything else. No other bearings in this price range are even close to as good and ya that means Bones too. BUY THESE!

fast, both delivery and the bearings. Muirskate, you guys are bad ass.
Break them in first
on 2018-08-07
These bearings are fast and great but DON'T race them out of the tube, these need several really good break-in runs because that grease it thicc. if you need to use a bearing fresh out of the package for a race i recommend looking to other bearings, but that being said, these will outlast the majority of other ceramics on the market, and once some of the excess grease is spun out, these things are monstrous!

They are cheap and the best bearings you can get
Fast and leaky?
on 2018-03-12 Verified Purchase
I think the must submerge these in lube, they come out of the tube sticky and gross like a newborn, leak like babies cry and shit, and take a while to get to their full potential.

I switch to Zealous ceramic bearings for a try on my Penny Board surprisingly it roll smoother and longer than the Penny ABEC 7. You won't regret after you try these bearings. The only thing bad is the lubricant overflow out and I have to wipe it clean after each ride.

These guys are long lasting, and have built in spacers. Plus, they're ceramic. While they aren't particularly faster than Zealous Greens, they're most definitely more durable, and fast af nonetheless. You can't go wrong with these!

They are the best bearings. Cheap Ceramics with built-in spacers. I never have to worry about water. A warning though. Mine where super loobed when I received them, and dirt stuck to the extra loob that dripped onto my wheel.

With every push you make.

You're going to enjoy it. I'm heavier and threw these on my tugboat. Yeah you heard it. I love the thing and it gets all kinds of love. Anyways. I wanted to try these for a long while. I have two other setups with the original Zealous Bearings and those are nice. These seem faster and have longer roll speed than the others. One push gives me decent length before I have to push again. I recommend these bushings above everything else that I've tried
Better than Reds
on 2017-02-23 Verified Purchase
I've used Reds before and they're good but they're a pain to install and require a lot of keep up to keep them working. These bearings are smoother, quieter, faster, cheeper, less maintenance, and easier to install. I've had them for almost a year and haven't cleaned them yet, it almost feels like they get better the more use they get. If your blowing through Reds like I used too switch to Zealous.

Cheaper, Faster, Simpler, Better
on 2016-09-25 Verified Purchase
Bought these to replace my bustin bearings after I rusted them out. These are so much better after breaking them in they're still quiet and so much faster than my old ones. Installing them is zero hassle because everything is built in. If you're looking for new bearings I highly recommend them, they are worth the money.

on 2016-07-25 Verified Purchase
Between my large soft wheels and these bearings you can't even hear my board coming unless the road is rough. I feel like they're noticeably smoother than the steel Zealous bearings, which I was already in love with. Can't attest to any differences in what they feel like at high speeds, but I have high hopes now.

Did the job well!
Good so far.

Hard to tell if they are significantly faster than the normal zealous, but I am going fast on them and they are very smooth. Zealous is the best bearing.
