Part SKU# TRB-MR85-RZ/C Chromium Steel Races Ceramic Si3N4 Balls Low Torque Start Up Dimensions as follows: ID, OD, Width: 5x8x2.5mm This Bearing is Compatible with Part #: Axial: AXA1213 Losi: LOSB1728 HPI: B020 Tamiya: 42111 Compatible with Traxxas: 5114 TLR: TLR23700 Team Associated: 31400 The Characteristic of Ceramic Balls Compared with steel, ceramic materials are noted for their better or particular characteristics, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
