Q:What does ABEC stand for?
A


A: This is an acronym for Annular Bearing Engineers' Committee.This committee determines the ratings for each bearing.The ABEC rating system includes grades 1,3,5,7, and 9. The number determines how much "roll"the bearings has. The higher the number, the longer it will take your wheel to stop spinning after you stop pushing. Also, SUN BEARING can provide various grades of bearings.
