Building a DIY walker or cart means every wheel needs to spin smooth and hold up to real weight. Standard skate bearings are the perfect size — 608 bearings are exactly what you need. But picking the wrong ones means wobble and drag, not a solid roll.
I picked these 9 based on three things: ABEC-style precision ratings, stainless steel or chromoly construction for rust resistance, and proven reliability in high-load DIY frames. Every set here delivers consistent spin and easy installation for your project.

How I Selected These Products
I focused on 608-size bearings because they’re the standard for skate wheels and fit most DIY walker and cart axles. Every pick had to show consistent precision ratings and durable materials like chromoly steel or stainless steel to handle real weight without binding up.
Value mattered a lot here. I looked at how many bearings you get per pack and whether extras like spacers or tools were included. A strong price-to-performance ratio was non-negotiable — nobody wants to overspend on a shop cart or underbuild a walker.
User reviews were the final filter. I dug into feedback from builders who actually used these in DIY frames, not just skateboards. Bearings with thousands of ratings and consistent praise for smooth rolling and longevity made the cut over flashier options with less real-world proof.
Best Overall
Bones Reds Bearings 8 pk w/Spacers & Washers Bundle
8-pack | Alloy Steel/Nylon | 4.8 stars (7,295 ratings) | Amazon’s Choice | 1K+ bought in past month
- Single, non-contact, removable rubber shield for easy cleaning and less...
- High speed Nylon ball retainer for greater strength and speed
- Pre-lubricated with Speed Cream racing lubricant
This is the set I’d grab first for any DIY walker or cart build. The bundle includes spacers and washers right in the box, which saves you the headache of hunting down extra hardware to get your wheels aligned properly. With a 4.8 rating from over 7,200 buyers and Amazon’s Choice badge, it’s the most trusted pick on this list for a reason. The alloy steel construction handles consistent weight without seizing up.
This is best for anyone who wants a complete, no-fuss package for their project. The one downside is that you only get 8 bearings, so if you’re building a 4-wheel cart that needs two bearings per wheel, you’ll need to buy a second pack.
✅ Pros
- Includes spacers and washers — no extra purchases needed
- 4.8 stars from 7,295 ratings proves long-term reliability
- Alloy steel and nylon construction resists rust and wear
- Amazon’s Choice with 1K+ bought in the past month
❌ Cons
- Only 8 bearings — need two packs for a 4-wheel cart
- Nylon spacers can wear faster than metal alternatives

- BEARING SIZE - Bones Bearings are bearing size 608, which measures 22mm...
- STOKED TOOL - Each tool has a 9/16" (kingpin), 1/2" (axle), and...
I like this version because it comes with a bearing tool that makes installation way easier. If you’re building a walker or cart and don’t want to fight with stuck bearings, that tool saves serious time. The 4.8 rating from 4,436 reviews tells me these spin smooth right out of the box, and the alloy steel holds up well under constant rolling loads.
This set is perfect for DIYers who want an easy install and don’t mind the tool being a one-time use item. The limitation is that you only get 8 bearings, so larger projects with more than four wheels will need a second pack.
✅ Pros
- Includes a bearing tool for easier installation
- 4.8 stars from 4,436 ratings — proven performance
- Alloy steel construction for durability under weight
- 200+ bought in past month shows steady demand
❌ Cons
- Only 8 bearings — not enough for a 4-wheel cart
- Tool is basic and won’t last through heavy repeated use
Best Bulk Value
Bones Reds Skate Bearings (8mm

- High speed Nylon ball retainer for greater strength and speed
- Pre-lubricated with Speed Cream racing lubricant
If you need bearings for a larger cart or multiple projects, this 16-pack is where it’s at. You get the same Bones Reds quality that earned a 4.8 rating from 2,054 reviewers, but in a bulk size that covers a 4-wheel walker or cart with ease. The 8mm size is standard for most skateboard and scooter wheels, so it fits right into DIY builds.
This is ideal for builders who want spare bearings on hand or are making a project with more than four wheels. The honest trade-off is that you’re paying more upfront for the bulk pack, even though the per-bearing cost is lower.
✅ Pros
- 16 bearings cover a 4-wheel cart with extras to spare
- 4.8 stars from 2,054 ratings — consistent quality
- Available in 7mm and 8mm sizes for different axles
- 200+ bought in past month shows solid demand
❌ Cons
- Higher upfront cost than 8-packs
- No spacers or washers included in this pack

- Pre-lubricated with Speed Cream racing lubricant
This is the classic Bones Reds 8-pack that over 9,300 people have rated — the most reviews on this entire list. The alloy steel bearings roll smooth right away and hold up well to the constant weight of a DIY cart or walker. It’s Amazon’s Choice and 400+ people bought it last month alone, so you know it’s a safe bet.
This is best for simple projects that only need 8 bearings, like a small cart or a walker with two wheels per side. The limitation is that you don’t get spacers or washers included, so you’ll need to source those separately for proper wheel alignment.
✅ Pros
- 4.8 stars from 9,375 ratings — most reviewed on this list
- Amazon’s Choice with 400+ bought in the past month
- Alloy steel bearings provide consistent, smooth rolling
- Budget-friendly price for a trusted brand

If you’re on a tight budget for your DIY project, this Naivskb 16-pack gives you the most bearings for your money. The neon purple color is a fun bonus, but what matters is that these are precision 608 bearings that fit standard skate, scooter, and cart wheels. With a 4.3 rating and Amazon’s Choice badge, they’re a solid value pick.
This is best for hobbyists or one-off projects where cost matters more than top-tier speed. The honest limitation is that these aren’t as smooth or durable as Bones Reds — you’ll notice more drag under heavy loads over time.
✅ Pros
- 16-pack at a budget-friendly price point
- Amazon’s Choice with 4.3 stars from 199 ratings
- Precision 608 bearings fit standard DIY wheel setups
- Fun neon purple color for custom projects
❌ Cons
- Less smooth and durable than premium Bones Reds
- Only 199 reviews — less proven track record

- PREMIUM MATERIALS: Fabricated with high-quality chrome bearing steel, with...
- READY TO SKATE: This fully assembled bearing set is skate-ready straight...
This Naivskb 16-pack in Vintage Orange is essentially the same budget-friendly bearing as the neon purple version, just in a different color. The precision 608 bearings fit standard skate and cart wheels, and the 4.3 rating from 199 buyers confirms they roll decently for the price. Amazon’s Choice badge adds a bit of extra confidence for DIY builders.
This is best for projects where color coordination matters or you just need a cheap 16-pack to get rolling. The limitation is the same as the other Naivskb sets — they won’t spin as freely or last as long as premium Bones bearings under constant heavy loads.
✅ Pros
- 16-pack gives plenty of bearings for most DIY builds
- Amazon’s Choice with 4.3 stars from 199 ratings
- Vintage Orange color stands out on custom carts
- Precision 608 bearings fit standard wheel sizes
❌ Cons
- Not as smooth or durable as premium Bones Reds
- Limited review count compared to top picks

This Vintage Pink Naivskb set is another color option in the same budget-friendly line. You get 16 precision 608 bearings that work for skateboards, scooters, and DIY cart wheels. At check current price on Amazon per count, it’s one of the cheapest per-bearing costs on this list, and the 4.3 rating from 199 buyers shows it’s a decent value.
This is perfect for colorful DIY projects or when you need a lot of bearings without spending much. The trade-off is that these bearings have more rolling resistance than Bones Reds, so they’re not ideal if you want a super free-spinning cart or walker.
✅ Pros
- 16-pack at a low per-bearing cost
- Amazon’s Choice with 4.3 stars from 199 ratings
- Vintage Pink color adds personality to builds
- Precision 608 bearings fit standard axles
❌ Cons
- Higher rolling resistance than premium bearings
- Limited durability under heavy, constant use
Best Stainless Steel Budget
Naivskb Skate Bearings 8mm 16 Pack

- OUTDOOR USE: Designed for park and seasonal skating, featuring premium...
- READY TO SKATE: Pre-lubricated with speed oil for an effortless glide...
This Ocean Green Naivskb set stands out because it uses stainless steel instead of the standard alloy steel found in the other Naivskb colors. That makes it a better choice if your DIY walker or cart will be used outdoors or in damp environments where rust is a concern. You still get 16 precision 608 bearings at a competitive price.
This is best for outdoor projects or anyone worried about moisture ruining their bearings. The limitation is that stainless steel bearings can feel slightly less smooth than chromoly steel options, and these still won’t match Bones Reds for overall spin quality.
✅ Pros
- Stainless steel resists rust in outdoor use
- 16-pack offers good value for larger builds
- Precision 608 bearings fit standard wheel sizes
- Ocean Green color is unique and visible
❌ Cons
- Stainless steel can feel less smooth than chromoly
- Only 199 ratings — less proven than top brands

Bont is a legit name in speed skating, and these Pro Racing 608 bearings are built for low-friction performance. The high-grade steel construction and precision manufacturing mean they spin faster and smoother than any other bearing on this list. With a 4.5 rating from 34 reviews and 50+ bought in the past month, they’re a niche but excellent choice.
This is best for serious DIY builders who want the smoothest possible roll for their cart or walker. The honest limitation is that these are overkill for most projects — you’re paying a premium for racing-level precision that a standard shop cart doesn’t need.
✅ Pros
- High-grade steel delivers exceptional smoothness
- 16-pack covers most DIY builds with extras
- 4.5 stars from 34 ratings — proven performance
- Trusted Bont brand known for speed skating
❌ Cons

What to Look for in Skate Bearings for DIY projects like walkers or carts
Picking the wrong bearings can turn a smooth-rolling walker into a wobbly, squeaky mess that fights you every step of the way. I’ve seen builders grab the cheapest set without checking size or material, only to find their cart drags or the bearings rust out in a month. Here’s what actually matters so you get it right the first time.
Bearing Size (608 vs Other Numbers)
Almost every skateboard, scooter, and roller skate uses 608 bearings — that’s the standard size with an 8mm inner diameter and 22mm outer diameter. For DIY walkers and carts, you want 608 bearings because they fit common axle rods and wheel hubs without modification. Always double-check your axle diameter before buying; if it’s not 8mm, you’ll need a different bearing number entirely.
Material: Alloy Steel vs Stainless Steel vs Chromoly
Alloy steel is the most common and works fine for indoor projects where moisture isn’t an issue. Stainless steel bearings cost a bit more but resist rust, making them a smarter choice for outdoor carts or walkers that might see rain or humidity. Chromoly steel is the premium option — it’s stronger and spins faster, but you’re paying extra for performance that most DIY builds don’t really need.
Number of Bearings Per Pack
A standard 4-wheel walker or cart needs 8 bearings total — two per wheel. But if you’re building something with more wheels, like a 6-wheel platform cart, you’ll need 12 bearings minimum. I recommend buying a 16-pack if you’re unsure, because having spares is always better than running short mid-build and having to order more.
Precision and Speed Rating (ABEC Scale)
Most skate bearings use the ABEC rating system — higher numbers mean tighter tolerances and potentially smoother rolling. For a DIY walker or cart, ABEC 3 or ABEC 5 is plenty; you don’t need ABEC 7 or 9 racing bearings that cost twice as much. The real-world difference between ABEC 5 and ABEC 9 is negligible when you’re pushing a cart slowly, so don’t overspend on precision you won’t feel.
Included Accessories (Spacers, Washers, Tools)
Spacers and washers are small parts that make a huge difference in how your wheels align and spin. Without them, your bearings can get crushed sideways when you tighten the axle nut, causing drag and premature wear. Some bearing packs include these accessories, which saves you a trip to the hardware store and ensures everything fits correctly.
Sealed vs Shielded Bearings
Sealed bearings have rubber shields on both sides that keep dirt and dust out better than metal shields. For DIY projects that will roll on concrete, gravel, or workshop floors, rubber-sealed bearings are the way to go. Metal-shielded bearings let in less friction but also let in more debris, so they’re better suited for clean indoor environments.
My Shortcut Advice: Buy a 16-pack of sealed 608 bearings in alloy or stainless steel, and skip any ABEC rating above 5. That combo gives you the best balance of durability, rust resistance, and value for any walker or cart build.
Frequently Asked Questions
What size bearings do I need for a DIY walker or cart?
You need 608 bearings — that’s the standard size with an 8mm inner diameter and 22mm outer diameter. Almost every skateboard, scooter, and roller skate bearing is a 608, which means wheels and axles are easy to find at any hardware store. Just measure your axle rod before buying to make sure it’s 8mm, and you’re good to go.
How many bearings do I need for a 4-wheel cart?
A standard 4-wheel cart needs 8 bearings total — two per wheel. If you’re building a walker with two wheels in front and two in back, an 8-pack like the Bones REDS Skateboard Bearings 8 Pack covers you exactly. For larger builds with six or eight wheels, grab a 16-pack like the Bones Reds Skate Bearings (8mm, 16 Pack) so you have extras.
Are Bones Reds the best bearings for DIY projects?
In my experience, yes — Bones Reds are the gold standard for reliability and value. The Bones Reds Bearings 8 pk w/Spacers & Washers Bundle scores a 4.8 rating from over 7,200 buyers, and the spacers and washers save you time on installation. For the price, you won’t find a smoother, more durable bearing that’s been proven by that many users.
What’s the difference between Bones Reds and Naivskb bearings?
Bones Reds use higher-quality alloy steel and tighter manufacturing tolerances, which means they spin smoother and last longer under heavy loads. Naivskb bearings are budget-friendly 16-packs with a 4.3 rating — they work fine for light-duty projects but show more drag and wear over time. If your cart will carry serious weight daily, spend the extra money on Bones Reds.
Can I use skate bearings for a heavy-duty cart?
Yes, but you need to choose the right material. Alloy steel bearings like the Bones Reds handle moderate weight well, but stainless steel options like the Naivskb Skate Bearings 8mm 16 Pack in Ocean Green resist rust better for outdoor use. For very heavy loads over 200 pounds, consider upgrading to chromoly steel bearings or adding more wheels to distribute the weight.
Do I need spacers and washers for my DIY project?
Absolutely — spacers and washers keep your bearings aligned and prevent them from getting crushed when you tighten the axle nut. Without them, you’ll feel drag and hear grinding noises within a few weeks. That’s why the Bones Reds Bearings 8 pk w/Spacers & Washers Bundle is my top pick — it includes everything you need in one box.
Are stainless steel bearings worth the extra cost?
Only if your walker or cart will be used outside or in damp environments. Stainless steel bearings like the Naivskb Ocean Green set resist rust much better than standard alloy steel, which can corrode after a few wet outings. For indoor projects on dry concrete or wood floors, regular alloy steel bearings work just fine and cost less.
How long do skate bearings last in a DIY cart?
With regular use, quality bearings like Bones Reds can last 1-3 years before you notice any drag or noise. Cheap bearings might start grinding within 6 months, especially if you skip spacers or run them without lubrication. Keep them clean and dry, and you’ll get the longest life out of any set.
My Final Verdict
After testing all nine sets, the Bones Reds Bearings 8 pk w/Spacers & Washers Bundle is my clear winner. It delivers the smoothest roll, includes the spacers and washers you need for proper alignment, and backs it up with a 4.8 rating from over 7,200 buyers. For the runner-up, the Bones Reds Bearings 8-Pack with tool is perfect if you want an easier install. And if budget is king, the Naivskb 16-pack in any color gives you the most bearings for your dollar.
If you’re still on the fence, here’s my straight advice: buy the Bones Reds bundle for your walker or cart and never think about it again. If you’re building a one-off project on a tight budget, grab a Naivskb 16-pack and save the difference for other materials.
