Ultimate Guide: Skateboard Bearing Size

Table of Contents

Ever wondered what makes a skateboard roll smoothly and fast? It's not magic, it's bearings! These little metal rings inside your wheels are super important. And when we talk about skateboard bearings, size is the first thing to know.

Skateboard Bearing Size: Understanding the 608 Standard

let's talk skateboard bearings! Imagine the wheels on your skateboard are like cars.

They need something to help them spin around and around super fast, right?

That's where bearings come in.

Bearings are these tiny, round things that fit inside your skateboard wheels.

They're like the secret ingredient that makes your board roll smoothly.

Without them, your wheels would barely turn, and skateboarding would be way harder – and way less fun.

Now, when it comes to skateboard bearings, there's a magic number you need to know: 608.

Think of 608 as the secret code for skateboard bearing size.

Almost every skateboard in the world uses this size.

It's like shoe sizes; there are different sizes for shoes, but for skateboards, 608 is the standard.

If you ever buy skateboard bearings, 99% of the time, they will be size 608.

So, what does 608 actually mean?

Well, it's all about measurements.

A 608 bearing is basically 8 millimeters wide on the inside hole (that's the bore), 22 millimeters around the outside edge (that's the outer diameter), and 7 millimeters thick (that's the width).

These numbers might sound a bit confusing, but just remember 8, 22, and 7.

These dimensions are important because they make sure the bearing fits perfectly into skateboard wheels and trucks.

It's like making sure you have the right size batteries for your toy; if it's too big or too small, it just won't work.

This standard size is great because it means you don't have to worry too much when buying bearings.

Whether you're getting new wheels, a new deck, or just replacing your bearings, size 608 will almost always fit.

It's the universal language of skateboard bearings.

Just like knowing how to do a snowboard carve is key to snowboarding, knowing 608 is key to skateboard bearings.

It simplifies things a lot!

Why ABEC Ratings Don't Matter for Skateboard Bearing Size

so now you know about the size 608, which is like the golden rule of skateboard bearings. But you might have seen bearings advertised with something called "ABEC ratings," like ABEC 3, ABEC 5, ABEC 7, and even ABEC 9! It sounds super important, right? Like the higher the number, the faster you'll go? Well, not really. Let me tell you a little secret: ABEC ratings are kinda overrated for skateboarding. It's like when you see a race car and think it must be the fastest car ever, but then you realize it's terrible for picking up groceries. ABEC ratings are like that – they sound fancy, but they don't really tell you what you need to know for skating.

Think of ABEC ratings like grades for how perfect a bearing is made in a factory. They measure tiny, tiny differences in how round and smooth the bearing is when it's brand new. We're talking about measurements so small, you can't even see them with your eyes – they use special machines to check! These ratings go up in numbers, like ABEC 1, 3, 5, 7, 9, and even higher. The higher the number, the tighter the tolerances *in theory*. But here’s the thing: skateboarding isn't happening in a super clean, perfect factory. It's happening on rough streets, skateparks full of dust, and sometimes even puddles! Those super tiny differences that ABEC ratings measure? They get lost the second you roll over a pebble.

ABEC: Sounds Fancy, Means Little

Imagine you're baking cookies. You could measure all your ingredients super precisely, like a scientist, to make sure they're exactly perfect. That's kind of like what ABEC ratings do for bearings – measure how precisely they're made. But if your oven is a bit uneven, or you accidentally drop a cookie on the floor, does all that super-precise measuring really matter anymore? Nope! It's the same with skate bearings. Even if a bearing is made to super-high ABEC standards, the real world of skateboarding is way less perfect. Dirt, impacts from jumps, and just general wear and tear will affect how your bearings roll way more than those tiny differences measured by ABEC.

What ABEC Really Measures (and Doesn't)

So, what does ABEC actually measure? It's all about manufacturing precision. ABEC ratings check things like how round the bearing is, how smooth the surfaces are, and how much wobble it has. These are all measured in microns – that's super, super tiny! A micron is one-millionth of a meter. Think about a human hair; it's about 50 microns wide. ABEC ratings are measuring things way smaller than that! Now, these tiny measurements are important for machines that spin at crazy high speeds in clean rooms, like in some factories. But skateboards? We're not spinning at thousands of RPM in a vacuum. We're rolling on concrete, wood, and asphalt, dealing with all sorts of gunk. ABEC ratings don't measure how well a bearing handles dirt, impacts, or sideways forces (which we call axial loads). And guess what? Those are the things that matter most for skateboard bearings!

Focus on What Actually Makes a Difference

If ABEC isn't the key to skateboard speed, what is? Well, it's more about the stuff that ABEC doesn't test. Things like the material the bearing is made from, the type of grease or oil inside, and how well the bearing is sealed to keep dirt out. Good skateboard bearings are made from strong steel, sometimes even ceramic for less friction and longer life. They have good quality lubricant to help them spin smoothly. And they have seals – little rubber or metal shields on the sides – to stop dust and grime from getting inside and messing things up. These things will make way more difference to how your skateboard rolls and how long your bearings last than any ABEC rating. Think of it like this: would you rather have a super-precisely measured cookie made with cheap ingredients, or a slightly less perfect cookie made with really good chocolate and butter? I'd go for the tasty cookie every time! And for skateboards, focus on bearings made with good stuff, not just a fancy ABEC number. You can even think about how to do a snowboard spin – it's about technique and quality, not just numbers!

Choosing the Right Skateboard Bearing: Size, Materials, and More

Size Still Matters (Because 608 is King)

so we've trashed talked ABEC ratings a bit. Does that mean size doesn't matter at all? Nope! Size still totally matters, but in a super simple way. Remember 608? That's still your main jam. Think of it like ordering pizza – you pretty much always want a regular size, right? 608 is the regular size for skateboard bearings. Almost every skateboard wheel out there is made for 608 bearings.

Now, are there *other* sizes of bearings? Yeah, technically. But for skateboards? Stick with 608. Using anything else is like trying to put a car engine in a bicycle – it's just not gonna work, and honestly, why would you even try? The beauty of 608 is that it's everywhere. Need to replace a bearing? Just grab a pack of 608s, and you're golden. It keeps things easy, like knowing how to do a - once you get it, you're set for fun.

Material World: Steel, Ceramic, and Hybrids

Alright, if ABEC is kinda meh, and size is just 'size 608 and done,' what *should* you think about when picking bearings? Materials! This is where things get a little more interesting. Most skateboard bearings are made of steel. Steel is tough, like really tough. It can take a beating, it's not crazy expensive, and it does the job. Think of steel bearings as your trusty old sneakers – reliable and get you where you need to go.

But then there's ceramic. Ceramic bearings are like the sports cars of the bearing world. They're lighter than steel, and they can roll faster with less friction. Imagine pushing your board and it just keeps going and going, almost like magic! That's kinda what ceramic bearings feel like. However, they're also pricier, like way pricier, and some skaters argue they're not as durable as steel for taking hard slams and street skating abuse. It's like choosing between a sturdy truck and a fast sports car - depends on what you're doing!

Then, you have ceramic hybrids. These are like the best of both worlds. They use steel for the outer rings (called races) because steel is strong, but they use ceramic balls inside. You get some of the speed and less friction of ceramic, but with more of the durability of steel. They're often a good middle ground if you want to upgrade without going full-on ceramic crazy. Want to feel upgraded in snowboarding? Think about snowboarding boards and wax - it's all about getting a bit better gear for a smoother ride.

Seals and Shields: Keeping the Bad Stuff Out

Last thing to think about: seals and shields. Bearings need to be clean to roll well. Dirt, dust, water – these are like the enemies of your bearings. Seals and shields are like little bodyguards for your bearings, keeping the bad stuff out and the good stuff (like grease) in. They're little covers on the sides of the bearing.

There are two main types: rubber seals and metal shields. Rubber seals, often called "2RS" (you might see 608-2RS), give you better protection against dirt and water. They make a tighter seal, like a good lid on a jar. Metal shields, sometimes called "ZZ" or just "Z" (like 608ZZ), are less protective against dirt but can have a tiny bit less friction than rubber seals. It's a small difference, though. Choosing between them is like picking snowboarding gloves and mittens - depends on the conditions. For messy, wet places, go for more protection.

For most skaters, especially if you're skating street or skateparks, rubber seals (2RS) are the way to go. They'll help your bearings last longer because they keep more gunk out. If you're skating indoors on super clean surfaces all the time, maybe metal shields are okay, but for real-world skating, seals are your friends. Think of them as a tiny investment in keeping your roll smooth and your skate sessions fun.

Rolling to the Finish Line

So, you've made it to the end, hopefully without your eyes glazing over from bearing talk. The big takeaway? Skateboard bearing size is pretty standard – 608 is your go-to. Don't get caught up in the ABEC rating game; it's mostly just marketing fluff for skateboarders. Focus on quality materials, good seals to keep dirt out, and the right kind of lube.

Choosing bearings shouldn't be a headache. Think about how you skate, where you skate, and how much you want to spend. A good set of standard-size bearings from a reputable supplier will probably do you way better than overpriced, high-ABEC ones. Now get out there and skate!
