ABEC 9 bearings specially designed to suit all your needs. Designed with high quality materials. One of the most common questions about bearings, is “What ABEC are those?” but a better question should be, what does ABEC mean? Basically ABEC is a rating system for the tolerances in a bearings. The higher the number, for example ABEC 9, the less the tolerance in the bearing. Having smaller tolerances means that your bearing will spin faster, for longer.
