Tornado F-3 Black SI3n4 silicon nitride Ball W/ Black Oxidized Races Bearings
Tornado's stage 2 hybrid bearings. Made of high-quality steel with oxidized races and black ceramic balls to create less friction and drag with better roll than all steel bearings.
Each set comes standard with the lime green dust shields and complimentary spacers. The full ceramics do not come with shields, as they are not designed to be used with them.
Size: 7mm, and 8mm
Comes as 16 bearings per set.
As with all bearings regular maintenance (cleaning/oiling) is required for optimal performance.
