Abec 3, Abec 5, Abec 7, Titanium, Ceramic? There are a lot of different kinds of bearings. Tristán’s family have an industrial bearings company since 1947, and he has been working for 17 years developing bearings for skateboards, 14 of these with his brand Mosaic. So there’s nobody better to answer some of the questions you usually ask in the skate shop.
What parts does a bearing have?
Outside and inner rings, balls, cage, cap and lubricant.
What is the ABEC of a bearing?
ABEC is the abbreviation of Annular Bearing Engineers Council, ABEC’s role is to establish tolerance standards in manufacturing. The higher the ABEC the more accurately each piece of the bearing is made. That is to say, if you were to look at it through a microscope, the smoother everything is. But the ABEC system does not include lateral load or impact resistance, so it is not enough just to have a very high ABEC rating for the bearing to be good for skateboarding. More important than the ABEC is the way it is manufactured, the materials used, and its quality.
