Shopping for skateboard bearings and wondering whether ABEC 7 is worth paying more for than ABEC 5? The numbers look like a speed ranking, but that's not really what they measure. Here's what matters when you're choosing bearings for street skating, skateparks and the less-than-perfect surfaces we get in the UK.
What does ABEC mean on skateboard bearings?
ABEC stands for Annular Bearing Engineers' Committee. It's a system for classifying the manufacturing precision of certain ball bearings. The familiar grades are ABEC 1, 3, 5, 7 and 9. A higher number means tighter specified dimensional tolerances, not a guaranteed faster skateboard.
ABEC 3 vs 5 vs 7 vs 9
ABEC 3: a lower precision grade; it doesn't tell you whether the bearing is good for skating. ABEC 5: tighter tolerances, but no automatic speed advantage. ABEC 7: tighter again, without proving superior durability. ABEC 9: the tightest of these familiar grades, but still not a complete quality score.
Two bearings with the same rating can feel very different because of their seals, lubricant, materials and construction.
Do higher ABEC bearings make your board faster?
Not necessarily. ABEC measures precision, not skateboarding speed. Bearings also face impacts, sideways loads, dirt and moisture. The ABEC grade doesn't rate those qualities. Wheel diameter, urethane and ground surface also affect how your board rolls. See our 52mm vs 54mm wheel guide for another part of the picture.
What matters more?
Bearings made for skating
Choose skate-specific bearings from a reputable manufacturer. Some established skate bearing ranges don't use ABEC numbers at all.
Protection from dirt and water
Shields and seals can help keep grit out, although no skateboard bearing should be assumed waterproof. UK rain and gritty paths make basic care worthwhile.
Lubrication
Use lubricant recommended by the bearing maker. A long spin in your hand isn't a reliable test of speed under a skater's weight. A dry bearing may spin freely unloaded but wear more quickly.
Correct installation
Most standard skateboard wheels take two bearings each. Seat them properly, follow the manufacturer's spacer guidance and check that axle nuts allow the wheels to turn freely without excessive play.
Which skateboard bearings should beginners buy?
For a first setup, prioritise sensible pricing, reputable skate-specific construction and easy maintenance over the biggest ABEC number. If your existing bearings roll smoothly, you might not need an upgrade at all. Browse FK's bearings collection when you do need replacements, and check our wheels collection if you're refreshing the rolling setup together.
When should you replace them?
Grinding, rough rotation, visible corrosion, seizing or damage are reasons to inspect. Clean and lubricate serviceable bearings according to the maker's instructions; replace damaged or badly corroded ones. If you've skated wet ground, dry your setup rather than leaving it damp in a bag.
Quick FAQs
Are ABEC 7 bearings better than ABEC 5?
They're manufactured to tighter tolerances, but that doesn't prove they'll skate faster or last longer.
Are ABEC 9 bearings worth it?
Sometimes, but not just because they're ABEC 9. For everyday skating, overall design and care matter more.
Do all good bearings have ABEC ratings?
No. Some well-regarded skate bearings don't use the system.
Should I replace all eight at once?
Not necessarily. Replace damaged ones, or fit a matching fresh set if several are worn.
The FK takeaway
Don't buy bearings by the number alone. Buy for skateboarding, maintain them and spend more time skating. Building a setup? Start with our deck size guide and browse FK's decks. Built by misfits. Made for everyone.
