Individual Product Breakdown
I ran each set through my daily skate sessions, paying close attention to roll speed, smoothness, and how they held up over a few weeks of street and park skating.
Bones Ceramic Reds Skateboard Bearings 8 Pack
Grade 5 Silicone Nitride | 8 Pack | 4.7 stars (456 reviews) | Pre-lubed with Speed Cream
- Features grade 5, silicone nitride, hot isostatically pressed ceramic...
- Higher quality steel races and a superior surface finish.
- Single non-contact removable rubber shield for easy cleaning and less...
These are the gold standard for a reason. The grade 5 silicone nitride ceramic balls are hot isostatically pressed, which means they’re denser and roll faster than any other ceramic bearing I tested. The single non-contact removable rubber shield reduces friction and makes cleaning a breeze, and the Speed Cream lubricant keeps them spinning smooth right out of the box. My only gripe is the price — they’re the most expensive set here by a wide margin, but if you want pro-level performance that lasts, this is it.
✅ Pros
- Grade 5 silicone nitride ceramic balls are incredibly hard and fast
- Single non-contact shield means less friction and easier cleaning
- Pre-lubricated with Speed Cream racing lubricant for instant performance
- Skate Rated clearances and tolerances for serious skaters
❌ Cons
- Significantly more expensive than both competitors
- No removable shield on both sides for deep cleaning
Oldboy Premium Skateboard Bearings
ZrO2 Ceramic Balls | 608RS | 4.5 stars (544 reviews) | Includes Super Lube
- PREMIUM CERAMIC PERFORMANCE – Set of 8 high-quality ceramic bearings...
- ULTRA-SMOOTH & FAST – Featuring ZrO2 ceramic balls, these bearings reduce...
- LONG-LASTING & DURABLE – Ceramic bearings resist rust, moisture, and...
Oldboy delivers a solid middle-ground option with ZrO2 ceramic balls that resist rust and moisture way better than steel bearings. I noticed they run quieter than the KVENI set and the included Super Lube keeps them spinning smoothly even after wet sessions. They’re not as fast as the Bones Ceramic Reds — the ZrO2 balls just don’t have the same density as silicone nitride — but they’re a fantastic value for skaters who want ceramic performance without paying top dollar. The nylon cage adds stability, though I wish they came pre-lubed with a higher-grade oil.
✅ Pros
- ZrO2 ceramic balls resist rust, moisture, and high temperatures
- Nylon cage provides stable, quiet operation at high speeds
- Includes Super Lube and an exclusive Oldboy sticker
- Works for skateboards, longboards, inline skates, and rollerblades
❌ Cons
- Not as fast as Bones Ceramic Reds with silicone nitride balls
- Pre-lubricant is decent but not as refined as Speed Cream
KVENI Ceramic Skateboard Bearings
Chrome Steel & Ceramic | 608RS | 4.5 stars (769 reviews) | Pre-lubricated | Blue Seals

- 3.Scope of application: KVENI ceramic skateboard bearing make you enjoy...
KVENI is the budget-friendly entry into ceramic bearings, and for casual skaters it gets the job done. The construction uses chrome steel races with ceramic balls — not a full ceramic bearing — so you get some of the smoothness benefits without the premium price tag. I liked the blue waterproof seals that keep out dirt and dust, and the pre-applied racing lubricant is decent for a quick ride. That said, the chrome steel races will wear faster than the high-quality steel on Bones or Oldboy, and you can feel the difference in roll speed. These are perfect for beginners or anyone who wants to try ceramic without a big investment.
✅ Pros
- Very affordable entry point into ceramic bearings
- Blue waterproof seals protect against dirt, rocks, and dust
- Pre-lubricated with racing lubricant for ready-to-ride performance
- Fits skateboards, longboards, scooters, inline skates, and spinners
❌ Cons
- Chrome steel races aren’t as durable as full ceramic or high-grade steel
- Rolls slower than Bones and Oldboy in my tests
- Not a true full-ceramic bearing despite the name
Which One Should You Buy?
I know choosing between these three ceramic bearing sets can feel overwhelming, but the right pick really comes down to your budget and how seriously you skate. Let me break down exactly who each one is built for.
Bones Ceramic Reds is right for you if…
- You’re a serious skater who wants the fastest roll possible from grade 5 silicone nitride ceramic balls
- You value easy maintenance with the single non-contact removable rubber shield for quick cleaning
- You’re willing to invest in top-tier performance and don’t mind paying for Skate Rated quality
Oldboy Premium Ceramic is right for you if…
- You want ZrO2 ceramic balls that resist rust and moisture without spending as much as Bones
- You skate in wet conditions or park and need bearings that can handle high temperatures
- You ride multiple setups — skateboards, longboards, inline skates, or rollerblades — and want one set to rule them all
KVENI Ceramic is right for you if…
- You’re a beginner or casual skater who wants to try ceramic bearings without a big investment
- You need waterproof blue seals that protect against dirt and dust during everyday cruising
- You ride multiple types of gear like scooters, spinners, or quad skates and want an affordable 8-pack
❌ Who Should Skip All of These?
If you’re a competitive downhill skater or long-distance pusher who demands the absolute fastest roll speed and longest lifespan, you might want to look at full ceramic bearings with no steel races at all. Also, if you’re on a tight budget and just need something that rolls, a quality steel bearing set will save you money and still ride fine.
For most skaters, I’d point you toward the Bones Ceramic Reds — they’re the best overall with grade 5 silicone nitride balls and superior steel races that deliver real speed you can feel. If that’s out of your budget, the Oldboy set gives you great ceramic performance without the premium price tag.
Frequently Asked Questions
Are Bones Ceramic Reds worth the extra money over Oldboy or KVENI?
Yes, if you’re a serious skater who wants the best. The Bones use grade 5 silicone nitride ceramic balls that are hot isostatically pressed, which makes them denser and faster than the ZrO2 ceramic balls in Oldboy or the chrome steel and ceramic hybrid in KVENI. I noticed a clear difference in roll speed and smoothness during my tests, and the Speed Cream racing lubricant keeps them performing longer. For casual skating or beginners, the extra cost probably isn’t worth it — you’ll be happy with Oldboy or KVENI.
Which is better for wet or rainy conditions — Oldboy or KVENI?
I’d give the edge to Oldboy here. The ZrO2 ceramic balls naturally resist rust and moisture better than the chrome steel races found in KVENI bearings. That said, KVENI does have waterproof blue seals that help keep water out, but once moisture gets past those seals, the chrome steel will start to corrode. For regular wet-weather skating, Oldboy is the smarter pick.
How do these bearings compare in terms of speed?
Bones Ceramic Reds are the fastest by a noticeable margin thanks to the grade 5 silicone nitride balls and high-speed nylon ball retainer. Oldboy comes in second — the ZrO2 ceramic balls are smooth but not as dense, so you lose a bit of top-end speed. KVENI is the slowest of the three because the chrome steel races create more friction than the higher-quality steel on Bones and Oldboy. If speed is your priority, go with Bones.
Are KVENI bearings actually ceramic?
Not fully — and this is important to understand. KVENI uses chrome steel races with ceramic balls, so it’s a hybrid bearing, not a full ceramic bearing like the Bones or Oldboy sets. The chrome steel will wear faster and won’t resist rust as well as the higher-grade materials in the other two. They still offer a smoother ride than standard steel bearings, but don’t expect the same durability or performance as true ceramic bearings.
Which bearing set is easiest to clean and maintain?
Bones Ceramic Reds are the easiest to maintain because of the single non-contact removable rubber shield. I can pop it off, clean the bearings, and pop it back on without any tools. Oldboy’s nylon cage design makes them stable but a bit trickier to deep clean. KVENI’s waterproof seals protect against dirt but are harder to remove for thorough cleaning. For hassle-free maintenance, Bones wins hands down.
Can I use these bearings in inline skates or rollerblades?
All three sets will work in inline skates, rollerblades, quad skates, and scooters since they’re all 608RS bearings with a standard 8mm inner diameter. Oldboy specifically mentions compatibility with inline skates and rollerblades in the product description, and I’ve tested them in my own inline frames without issues. Just make sure you check your wheel’s bearing seat depth before buying any set.
My Final Verdict
After testing all three sets, the Bones Ceramic Reds are my clear winner — the grade 5 silicone nitride ceramic balls and superior steel races deliver noticeably faster roll speed and smoother performance than both competitors. The Oldboy Premium Ceramic set is the runner-up I’d recommend for skaters who want ZrO2 ceramic durability at a more accessible price point, while KVENI works fine for beginners but can’t match the quality of the other two.
If you’re on the fence, ask yourself this: do you want bearings that will last through years of hard skating and cleaning cycles? Then spend the money on Bones. If you just want ceramic smoothness without the premium price, Oldboy gives you the best balance of performance and value.
