What are ABEC ratings?
Most bearings are measured by an ABEC rating. The higher the ABEC rating, the more accurate and precise the bearing will be. This rating system includes grades 1, 3, 5, 7, and 9. The ABEC rating does not specify many critical factors, such as load handling capabilities, ball precision, materials, material Rockwell hardness, degree of ball and raceway polishing, noise, vibration, and lubricant. Due to these factors, an ABEC 3 classified bearing could perform better than an ABEC 7 bearing.
ABEC 1 skateboard bearings tend to be the least expensive, the most crude, and the least accurate. The quality of the steel is not very high.
ABEC 3 skateboard bearings are generally inexpensive and do not roll smoothly or quickly.
ABEC 5 skateboard bearings are standard for most types of skateboarding. This rating gets you a fast speed at an affordable cost.
ABEC 7 skateboard bearings are very fast, smooth, and cost slightly more.
ABEC 9+ skateboard bearings are extremely fast! They are great for downhill skating and skaters that want to move insanely fast.

There are a handful of companies that do not use the ABEC rating scale, such as Bones Bearings. Bones Bearings uses their own rating system known as Skate Rated. Their bearings do not follow the ABEC ratings because they are superior in performance and the ABEC rating ignores many quality factors on which Bones Bearings prides itself.
