Oust Speed Oil is a proprietary lubricant manufactured from straight chain carbon molecules with at least 6 carbon atoms being used as a boundary layer lubricant. Under high temperatures created from frictional drag, these molecules form a metallic soap which become a tenacious lubricant film of increased viscosity to reduce the wear in the boundary region.
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.
If no MET-OL is purchased along with the bearings, the proper lubrication maintenance schedule with MET-OL is not followed, and/or other lubricants are used, the OUST bearing warranty will automatically be VOID. Also if the bearings aren't purchased directly through Oust bearings then no refunds will be given. This matter must be taken up with the company where the original transaction was made.
