The Best Shields for Your Skateboard Bearings
The Big Problem with Dirty Bearings
Are your skateboard wheels slow? Do they make funny sounds? Your bearing shields might be bad. Dirt gets in. Water gets in. Your bearings get stuck. You can’t go fast. You can’t do tricks. Your skateboard stops being fun.
Dirt in your bearings is bad. It makes them go slow. It makes them break fast. When dirt gets in, you have to clean them all the time. That costs money. That takes time.
Why This Gets Even Worse
Bad shields make big problems. Your bearings get:
- Rusty – water gets in
- Slow – dirt makes drag
- Noisy – grit makes sounds
- Short life – you buy new ones too much
Tests show that bearings with bad shields only last 200-400 miles. Good shields can make them last 600-900 miles! That is a big difference.
When your bearings are slow, your whole ride is bad. Your tricks don’t work. You get tired pushing more. You waste money on new bearings all the time.
The Perfect Solution: The Right Bearing Shields
Good news! The right shields fix all these problems. Market Union shields are made for skaters who want the best ride. We have been making shields since 2004. We know what works.
Our metal shields are made to exact specs. They keep dirt out but let your bearings roll fast. They make your skate time more fun with less work.

Types of Bearing Shields
Let’s look at what kinds there are:
Shield Type | Good Things | Not So Good | Best For |
---|---|---|---|
Rubber Shields | Not much drag, easy to clean | Water can get in | Street skating |
Metal Shields | Keeps water out, very strong | A bit more drag | Rough places, wet days |
No Shields | Fastest for a short time | Gets dirty fast, breaks soon | Race day only |
Why Metal Shields Win
Our metal shields win for most skaters. Here is why:
- Last longer – Metal shields can make bearings last 2x longer than ones with no shields or bad shields.
- Keep water out – Skate in wet? Metal shields help.
- Less cleaning – You don’t need to clean as much.
- Save money – Buy once, not many times.
Our Shield Making Process
We make our shields with care:
- We pick the best steel – only top grade
- We use smart machines that cut perfect every time
- We test every batch to make sure they fit right
- We clean them so there is no dirt or oil
Our quality control process makes sure you get only the best shields. We check for:
- Right size (we use special tools)
- No sharp bits
- Clean with no dirt
- No rust or marks

Skateboard Bearing Shield Tests
We test our shields to make sure they work. In one test, bearings with our shields kept 98% of their spin after 100 miles. Bearings with no shields lost 25% of their spin in the same test.
Shields for Different Skating Styles
Not all skating is the same. We make shields for all kinds:
- Street Skating – Low drag metal shields that still keep dirt out
- Park Skating – Strong shields that take hits
- Downhill – Extra tight shields for top speed and no wobble
- Wet Days – Full seal metal shields that keep all water out
How to Pick the Right Shields
Ask these easy things:
- Where do you skate most? (Street, park, hills)
- Is it wet where you live?
- Do you like to go fast or do tricks?
- How often do you want to clean your bearings?
Your answers tell you what shields you need. Most skaters need our carbon steel shields that work well for all types of skating.
What Top Skaters Use
Pro skaters pick their gear with care. Most pick metal shields for:
- Less time fixing, more time skating
- Bearings that last all season
- No rust when it rains
- Smooth roll that stays smooth
How to Care for Shielded Bearings
With our shields, care is easy:
- Clean them just two times a year (not every month!)
- Use the right oil (we can tell you which)
- Don’t take the shields off if you don’t need to
- Keep them dry when not skating
Skaters who use our shields save about $25 a year on cleaning kits. They also save time not having to clean so much.
The Cost of Good Shields vs. Bad Shields
Let’s do the math:
- Cheap bearings with bad shields: $15 but you buy new ones 4 times a year = $60
- Good bearings with our shields: $25-40 once a year = $25-40
You save money with good shields!
