Bones Swiss "roller skate bearings"  have the best reputation in the skateboard industry, and have had this honor for the past 28 years because of their performance and quality. Everyone who rides Swiss knows how fast they are, and most also comment on how long they last, typically several times as long as low cost bearings. Skaters who use Bones Swiss do so because they want the very best equipment they can get and they know the difference between ordinary and exceptional. Our team is a who’s who of top skaters and we are proud to be associated with each one of them.

In particular, the ABEC rating says nothing about how well a nsk bearing handles axial (side-to-side) loads, which are severe in most skateboard applications. Many companies do not show the ABEC rating, such as Bones Bearings, which makes bearings specifically for skateboarding, often marketed as "Skate Rated". Each bearing usually contains 7 steel or ceramic ball bearings, although other configurations are used as well.

There are 5 Abec ratings. An ABEC Rating refers to the Grade of the Bearing in Reference to smoothness and Noise. The quieter the Bearing and the TIGHTER the TOLERANCES between the Radial Ball Run -In and the Run-out - the Higher the Abec Rating. Most Industrial Bearings, such as Grinders - Drills - Routers etc. use Grade Abec-1. An Automotive Manual Transmission would use an Abec 3. Medical equipment might use an ABEC 5. 

The Rocketship to the Moon might use an ABEC 9 - However Jet Engines in the past have used an Abec 1 High Velocity Bearing. Abec is about Quality of Tolerances and an Abec 7 is not faster than an Abec 1 - What makes a Bearing fast is a lighter weight Lubricant. If you use a lightweight Oil it will dissipate faster than grease and you must remember to RE-OIL your Bearings on a regular Basis - Like every Saturday if you skate everyday or every other saturday if you skate 3 times a week - If the Bearings are loud when they spin, they are dry and you need to oil your Bearings before they disentigrate from friction.

Depending on how fast you want your ntn bearings to go you must decide on OIL (The fastest) or GREASE  (The least Maintenance) If you dont keep oil or grease in the Bearings they will run Metal to Metal and will seize from Friction and Heat and break apart. See the guide on Bearing Maintenance.
