ABEC 7/ MOC 5 BEARINGS
- Specifically designed for street skating by modifying the races to withstand the torsional loads inherent to skateboarding: they spin faster and last longer than standard bearings, particularly high-rated ABEC ones.
- The balls and races are both hardened to 50-plus Rockwell hardness. In addition, the internal pieces have a highly tuned, slightly unequal hardness that prevents them from grinding each other apart.
- The protective shields have 2 key design features: small holes to maintain lubrication without having to remove them, and tapered grooved edges where the shield meets the bearing in order to reduce drag, allowing more speed.
- Their steel shields do not dent the same way the standard cheap Aluminum shields do, often ruining bearings before they're even ridden.
- Oust has an exclusive on a patented oil. This extremely light lubricant fundamentally consists of 16-carbon chain molecules floating in a carrier oil that fills the micron-sized pits (porosity) in the steel races and balls. The micro carbon's triple bonds yield a molecular rigidity that enhances many of its functions, including a coating action that helps protect the bearing from rust and wear.
- All Swiss CNC machines are used to hone the races to tolerances within 1/30 th of a human hair, or .0001".
- The balls are rated with a grade 10, or better. This designates the roundness, consistency/concentricity, and weight uniformity of balls. Most imports have a grade 15 rating, while a space shuttle part may require something like a grade 5.
- The balls have a high degree of RA-finish, yielding a mirror finish and minimal pit-sizing for a smooth, fast ride.

- The balls have a high degree of RA-finish, yielding a mirror finish and minimal pit-sizing for a smooth, fast ride. The MOC 7's have even a better finish than the MOC 5's.
