R1 10X Double Ceramic Coated Bearing W/Si3N4 Balls (2pcs)

Upgraded 540 motor endbell bearings with 10X Double Ceramic coating & Si3N4 Balls . 

Double Ceramic (ceramic coated) 540 Motor Bearing  (R2 ⅛ x ⅜ x 5/32) 

Both the inner and outer races are hardened bearing steel, coated with our super slippery proprietary Double Ceramic (ceramic coating), resulting in 10x less friction than the low friction silicon nitride.The balls are Silicon Nitride. (Si3N4)  80% less friction and 40% less weight relative to steel.  This bearing uses a custom molded cage (the part that houses the balls) designed to retain lubrication and minimize vibration at high RPM. Altogether, every single part and surface have been re-designed to create the most precise, fastest, lowest friction bearing we can build. This bearing has significantly less friction even when compared to our full ceramic bearings.

Construction
Full ceramic balls and ceramic coated stainless steel inner and outer races.

To increase the life of this bearing it is recommended to lubricate the bearing everyday it is used, and also do not clean with any acetone based cleaners. We recommend using isopropyl alcohol to clean.
