Speed and cleanliness have always been two major issues in the Manufacturing process. The Moc 9 Airrr... addresses both issues. Manufactured with the highest quality USA 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 any oil leakage that might occur on a standard bearing seal. The Moc 9 design changes put the Airide a step ahead of all other bearings.

All OUST Bearings come lubricated from the factory with MET-OL Synthetic speed oil. All MOC Series bearings should be lubricated every 6 hours of use with MET-OL Synthetic speed oil. When skating slalom, down hill racing  or distance racing the bearings should be lubed every 2 hours of racing.
