Don't forget to protect your new set of Oust Moc 9's with Oust Speed Lube. 
Here is some technical information supplied by OUST:
Speed and cleanliness have always been two major issues in the Manufacturing process. The Moc 9 ... addresses both issues. Manufactured with the highest quality made balls, finer polished raceways and a seal system that is different from all other methods of bearing seals in the bearing industry at the present time.
 
The Moc 9 Buna Non-Contact Seal is set into a U-channel design in the outer race and a stop on the inner race to keep all foreign particles out of the ball area. It also stops oil leakage that might occur on a standard bearing seal. The Moc 9 design changes put it a step ahead of all other bearings.
 
The Only Bearing Engineered Specifically for Skateboards.  After several years of research Oust Inc. has developed a hybrid skateboard bearing named the" MOC SERIES".
 
These bearings meet all the critical factors for aggressive skateboarding. Unlike the common 608 bearings that are presently being used in the skateboarding industry which only require a radial load roll-out, OUST Inc. has designed a hybrid bearing which meet all the criteria for Static, Dynamic and Impact loads as well as bearing misalignment caused by torque. The OUST MOC Series bearings are the FIRST bearing manufactured for skateboarding that achieve a matched coefficient of friction between radial load roll-out and tortional load roll out.
