Set of 14 high-performance ceramic ball-bearings for XRAY T2 and T3 cars. Set of 5x10x4 bearings (10pcs) and 10x15x4 bearings (4pcs).
Ceramic bearings have many advantages over standard steel bearings, such as decreased weight, higher RPM capabilities, increased corrosion and wear resistance, as well as reduced friction and vibration. Ceramic bearings are fitted with Si3N4 silicone nitride ceramic balls. These ball-bearings are degreased and lightly oiled with AeroShell Fluid 12™ oil for maximum smoothness, long life, highest tolerance and maximum performance.
