Silicon nitride ceramic ball bearings have the following advantages:

• Low density, lightweight, 59% lighter than steel balls, reducing the centrifugal force during bearing operation, thereby reducing friction.
  
  
• The coefficient of thermal expansion is low, 1/4 of that of steel, and it can withstand drastic changes in temperature.
  
  
• The modulus of elasticity is 40% higher than that of steel, and there is less elastic deformation after stress, which reduces the vibration of the machine tool.
  
  
• Low friction coefficient, high-temperature resistance, and long service life.
  
  
• Non-magnetic, electrically insulated, and there is no adhesion and wear.
