» Bearings for high speed operations Evolution
Bearings with only the rolling elements made of ceramics are mainly used for high speed applications Typical properties of silicon nitride are: low density, 40 % of that of steel small thermal expansion, 29 % of that of steel high modulus of elasticity, 151 % of that of steel great hardness, HV10 at 20 °C is 1,700 compared with 700 for
