5x10x4 Halo ceramic bearing by Avid Racing Concepts is the standard bearing for 1/8th nitro clutches. A ceramic can spin at higher rpms with less drag and the life of the bearing is far greater than a steel bearing but in our industry we suggest that you maintain them with oil or grease every half-gallon to a gallon for the longest life possible. Another benefit to ceramics is the weight difference in the balls allowing for less rotating mass.
