Walk into any skate shop and you’ll see bearings labeled ABEC 3, ABEC 5, ABEC 7, sometimes even ABEC 9 — and the assumption is always that higher means faster. It’s a reasonable guess, and it’s also mostly wrong for skateboarding. Marketing leans hard on that number because it’s simple to print on a package, but it was never designed with skateboarding in mind. Here’s what the rating actually measures, why it matters less than most riders think, and what really determines how your bearings perform.
What ABEC Actually Measures
ABEC stands for Annular Bearing Engineering Committee, and the rating scale (1, 3, 5, 7, 9) measures manufacturing tolerances — how precisely a bearing is machined, particularly for high-speed, high-precision applications like industrial machinery. It says nothing about load handling, material quality, or how well a bearing performs under the sideways impacts and dirt exposure that skateboarding actually involves. A higher ABEC number means tighter manufacturing precision, not necessarily a better skateboard bearing.
Why ABEC Doesn’t Translate Well to Skating
The ABEC standard was designed for bearings spinning in one direction under a controlled, sealed environment, like inside a motor. Skateboard bearings take side-loading from turns and landings, get exposed to dirt, water, and debris, and stop and start constantly — none of which the ABEC scale accounts for. This is why a lot of skate-specific bearing brands either downplay their ABEC rating entirely or skip it in favor of their own performance ratings.
What Actually Determines Bearing Performance
Material Quality
Steel and ceramic are the two common ball materials. Ceramic balls are lighter, harder, and handle heat better, which can mean less friction over time, but they’re also more expensive and typically overkill for casual or beginner riders.
Shield Type
Removable rubber or metal shields keep dirt and moisture out while still allowing you to clean and re-lubricate the bearing. Fully sealed bearings protect better short-term but are harder or impossible to service once they get dirty inside.
Lubrication
The oil or grease inside a bearing has a bigger day-to-day impact on how fast and smooth it feels than the ABEC number does. Bearings that feel sluggish are very often just due for a clean and re-lube rather than actually being low quality — our How to Clean Skateboard Bearings guide walks through the process step by step.
Build Consistency
Reputable skate-specific brands generally test and build bearings around real skateboarding conditions rather than chasing an ABEC number, which is part of why a well-known skate brand’s ABEC 3 bearing can easily outperform a generic ABEC 7 bearing from an unknown manufacturer.
So What Should You Actually Look For?
- A reputable skate-specific brand rather than the highest ABEC number you can find
- Removable shields if you want to be able to clean and maintain them over time
- Steel bearings for most riders — they’re durable, affordable, and perform well for everyday skating; save ceramic for if you’re chasing marginal speed gains
- Regular cleaning over chasing a “better” bearing — maintenance affects performance more than most riders expect

Signs Your Bearings Need Attention
A grinding or gritty sound, noticeably slower roll than usual, visible rust after wet riding, or a wheel that doesn’t spin freely when lifted off the ground are all signs it’s time to clean or replace your bearings — regardless of what ABEC rating is stamped on them. This is part of a broader maintenance routine that’s worth doing regularly rather than reactively; see our Skateboard Maintenance Checklist for how bearings fit into overall board upkeep.
Bearing Spacers and Speed Rings
Two small parts often get overlooked when riders focus entirely on the bearing itself. A bearing spacer sits between the two bearings inside a wheel and keeps them from getting crushed when you tighten your axle nut, which prevents binding and premature wear. Speed rings sit on the outside of the bearing against the axle nut and truck, reducing friction at that contact point. Neither part is expensive, but skipping them can shorten the life of even a high-quality bearing considerably.
Bearings Matter for More Than Just Skateboards
The same core principles apply to longboard wheels and even motorized setups, where bearing quality affects how efficiently the wheel spins under load. Whether you’re running a standard street setup or something heavier, clean, well-lubricated bearings with the correct spacers will outperform a flashy ABEC number every time.
Frequently Asked Questions
Should I buy the highest ABEC rating I can afford?
Not necessarily — a higher number reflects manufacturing tolerance, not skateboarding-specific performance. A quality skate-specific bearing with a lower ABEC rating often performs better in real riding conditions.
Do ceramic bearings actually make you faster?
They can reduce friction and handle heat better than steel, but the difference is usually marginal for casual and intermediate riders, and much less important than keeping your bearings clean.
How often should I clean my bearings?
Roughly every few weeks for regular riders, or sooner if you’ve been skating in wet or dirty conditions, since debris buildup is the biggest everyday performance killer.
Are expensive bearings always better?
Not automatically. Build quality and maintenance matter more than price alone, and a well-maintained mid-range bearing often outperforms a neglected premium one.
What ABEC rating do most skate-specific brands use?
Many popular skate bearing brands sit around ABEC 3 or ABEC 5, or skip the rating system entirely in favor of their own internal performance testing.
Final Thoughts
The ABEC number on the box is one of the least useful things to base a bearing purchase on for skateboarding. Focus on a reputable skate-specific brand, keep your bearings clean, use the correct spacers, and you’ll get more real-world speed and smoothness than chasing a higher rating ever will. It’s a small, inexpensive part of your setup, but getting it right pays off every single session.
