Products - Skate Bearings the Truth

What is it?

It stands for Annular Bearing Engineers’ Committee, which 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, which for a 608 bearing determines:

  1. How close the bore is to 8mm in microns
  2. How close the outer diameter is to 22 in microns
  3. How close the width is to 7mm in microns
  4. The Rotating accuracy in microns

Does ABEC affect speed?

The simple answer - NO! - as ABEC measure tolerances the fit of wheels and axles have a much greater effect on performance. On the whole wheels and axles have extremely loose fits that allow you to press the bearings into the wheel by hand. This loose fit allows slippage between the wheel and bearing or the axle and bearing, the result of which is lost energy. Lost energy is lost speed!

What can affect speed?

Speed is first and foremost affected by the choice of lubricant.
