Skateboard Bearing : What is it?
| Skateboard bearings are the metallic cylinders enclosing the wheels of a skateboard. They consist of an inner central shaft fitting around the truck axles and an outer shaft fitting into the wheels. In between the inner and outer shafts are small balls, usually made of steel or ceramic, rolling in a raceway. Skateboard bearings increase the a skateboard’s performance in rough and rugged surfaces. |

Kinds of Skateboard Bearings include the following: |
Shielded Skateboard Bearings
- Shielded Skateboard Bearings are designed with shields to prevent grime and dirt from getting into the wheels.
- However, they are not dust- or watertight.
- They come in different bearing systems such as two metal shields, one metal shield and one pop-out cap, and two pop-out caps.
Sealed Skateboard Bearings
- Sealed Skateboard Bearings have heavily greased lip seals made of rubber or Teflon.
- They provide excellent protection against solid elements on the ground.
- They are resistant to water and dust.
- They can last for a long time without any maintenance.
- However, they have a high rolling resistance.
- They are also very expensive.

Bearing ratings: Choose skateboard bearings with a high Annular Bearing Engineering Council (ABEC) rating. They are rated using the odd numbers from one to nine in the ABEC scale, where one is the lowest and nine is the highest. Cheap skateboards usually come with unrated bearings that do not ensure excellent performance.
Maintenance advice
Do not skate on dirty or muddy surfaces, as skateboard bearings wear easily and slow down when exposed to too much dirt and water.
Replace rough bearings immediately. Nothing can be done to bring them back to their original form.
Clean your skateboard bearings regularly to keep them in top form.
