The Revolver ceramic series of bearings are superior quality Chrome Steel bearing with metal shields on both sides and Si3N4 Silicone Nitride Balls. These bearings are a great bearing for clutches requiring this size or for any free spinning application. Ceramic bearings can spin at higher RPMs and have less drag than chrome steel balls as well as the life of these bearings will be much greater when properly maintained.
The Assault Team has put these bearings through the most intense and demanding environments to ensure the best results on the track. We also recommend using the Assault RC B-Lube Bearing Oil (ARC81001)
