RC Brushless Motor Ceramic Lightning bearing kits have ABEC #5 tolerances, stainless steel races, retainers and shields with ceramic balls. Ceramic hybrids are lighter, have less rolling resistance and can sustain higher operating temperatures than traditional bearings. All Ceramic Lightning bearings are packed in grease and will require a short break in period to loosen up. Grease can be removed before shipping upon request....more

Q: Are greased bearings lubed for the life of the bearing?

A: No, traditional steel bearings always need lubrication to have a long life and lubrication will always be reduced over time as it will dissipate with use. How fast the lubrication dissipates varies greatly depending on RPM, operating temperature, operating environment and set up. If you have a particularly high temp application we would need to know the operating temperature to suggest suitable lubrication.
