BearingBearingWhat are ABEC RatingSkateboard bearings are measured by an ABEC rating, which rates the quality of materials and precision used in manufacturing the skateboard bearing. The higher the ABEC rating, the more precise the bearing will be. This rating system includes grades 1, 3, 5, 7, and 9. The closer you get to an ABEC 9 rating, the more speed and less friction your skateboard will have. Here are some general guidelines for ABEC ratings.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.
