How can we improve?
Firstly we have to regrettably say that the abec8, abec10, abec12, abec13, abec14 and abec15, 18, 20 you often see in the market are wrong abec grades. If you want to know the truth, we should firstly know what is abec grade.
The ABEC scale is a system of rating the manufacturing tolerance of precision bearings. The system was developed by the Annular Bearing Engineering Council (ABEC), a division of the American Bearing Manufacturers’ Association ABMA). The ABMA was formerly known as the Anti-Friction Bearing Manufacturers’ Association. Bearings rated under the ABEC systems are typically called “precision bearings”, with a rating or class from 1 to 9. ABEC 1 meets a looser tolerance and ABEC 9 meets high precision tight bearing tolerances.
Special announcements: We explain the real meaning of abec grade and just hope to tell us the truth. In fact, if customers need these bearings, we can print the abec grade you want to show on the bearing covers. We’re a skateboard bearing manufacturer. Most of our customers are skateboard accessories dealers. We know that sometimes some companies have to print higher abec grade on the bearing for promoting purposes.
