Best Skateboard & Longboard Bearings Guide

Most riders don’t think about skateboard bearings until their wheels start sounding gritty or slowing down faster than they used to. But bearings are one of the biggest factors in how fast and smooth a board actually rolls — more than wheel hardness, more than deck weight, and often more than riders expect.

Standard Skateboard Bearing Size

Nearly all skateboard and longboard wheels use the same standard bearing size: 8mm bore, 22mm outer diameter, 7mm width — commonly labeled as a 608 bearing. This is true across almost every skate board bearings brand and price point, which is why bearing sizes skateboard shoppers search for usually come back to this same standard fitment regardless of wheel brand.

Steel vs Ceramic Skateboard Bearings

• Steel skateboard bearings are the standard choice — durable, affordable, and perform well for most riders across street, park, and cruising use.
• High end skateboard bearings often use ceramic or hybrid ceramic balls, which spin with less friction and hold speed longer, especially noticeable in longer pushes or downhill riding.

For casual and everyday skating, quality steel bearings are more than enough. For downhill, longboard cruising, or riders chasing every bit of extra speed, ceramic or hybrid ceramic bearings offer a real, noticeable upgrade.

Longboard Bearings vs Standard Skateboard Bearings

Longboard bearings use the same standard 608 size as skateboards, but longboard riders tend to prioritize sustained speed and smooth rolling over quick acceleration, which is why ceramic and hybrid ceramic upgrades are especially popular in the longboard community — the benefit compounds over longer distances.

Signs Your Skateboard Bearings Need Replacing

• Wheels sound gritty or rough when spun by hand
• Noticeably reduced roll distance compared to a fresh push
• Visible rust on the bearing shield (common after riding in wet conditions)
• The board feels like it requires more effort to maintain speed

How to Maintain Skateboard Bearings

Skate bearings pick up dirt and moisture constantly, especially street and park riding. Removing and cleaning bearings periodically, then re-lubricating with a light bearing oil, extends their life significantly — but once a bearing starts making noise even after cleaning, it’s usually time to replace it rather than keep servicing it.

Final Thoughts

Whether you’re running budget steel bearings or upgrading to high end skateboard bearings for maximum speed, matching the correct 608 size and choosing the right material for your riding style makes the biggest difference.
