    The ABEC scale is a system for rating the manufacturing tolerances of precision bearings.

    Tolerance is the amount of variation from an absolute exact measurement that is permitted during the manufacturing process.

    Does abec 7 go faster than abec 5 no.. unless you are going 300mph then tolerance and speed dont really do anything.

    i believe it is just the model number. ABEC 5 is in the middle for preformance.

    Not much. They measure the precision for high speed machinery, but don't make a difference unless you get up into 300 mph.
