Bearing Information



What are bearings?

Bearings sit in the wheel hub and are what allow the wheels to roll in the skates. Most bearings are rated using the ABEC rating system. The higher the bearing rating, the better the bearing is.

WHAT IS ABEC?

ABEC stands for Annular Bearing Engineers' Committee. It is NOT a brand of bearing. This committee works to determine the standards for bearings for the Anti-Friction Bearing Manufacturers Association (AFBMA). The ABEC scale classifies different accuracy and tolerance ranges for bearings. There are 5 ratings: ABEC 1, ABEC 3, ABEC 5, ABEC 7, and ABEC 9.

The ABEC rating of a bearing is determined by the following:
How close the bore is to 8mm in micorns
How close the outer diameter is to 22 in microns
How close the width is to 7mm in microns
The rotating accuracy in microns

Does ABEC Affect the Speed of your Skates?

No, not unless you are skating at 330 mph. Only in extremely high speed applications like high speed motors and precision measuring instruments can bearing above ABEC 1 affect speed. Regardless of how fast you plan to go, speed is affected first and foremost by lubrication.
How fast you go is up to your ability, higher rated bearings will not make you go faster, but you do have more ROLL OUT. Another way to put this is how long it takes for the wheel to stop spinning, higher rated bearings will spin longer after you stop pushing.


What does bearing
lubricant do?

It keeps the metal parts from wearing against one another and keeps dirt away from the sensitive inner workings. If you use grease, it is thicker and acts as a seal against dirt, but at the same time it can increase torq and slow down the bearings. If you use oil, it is susceptible to dust and will need to be serviced more often. A bearing lubricant or cleaner is recommended over using any household chemical to lubricate or clean them. Household cleaners may seem like thy are doing the job, but in reality they are slowing down the bearings.
