AVID 5x10x4 Metal Bearing

The AVID 5x10x4 Metal Bearing (MR105ZZC) is a high quality steel/chrome bearing.  That includes a metal shields and silicone nitride ceramic balls (Si3N4). 

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.  However, in our industry we suggest that you maintain them with oil or grease every half-gallon to a gallon for the longest life possible.
