Introduction

The lighter specific gravity of pressureless sintered silicon carbide bush can make the weight of the bearing lighter, thereby reducing energy consumption. Its extremely high hardness makes the surface of the all-ceramic bearing smoother, the geometric shape is better, and the running noise is reduced, making the equipment more precise, harder and more resistant to strong corrosion, and directly prolongs the service life of the bearing.

Silicon Carbide Bearing Bush Features

  • High hardness makes it an extremely abrasion resistant material
  • High thermal conductivity, high tensile strengh and low thermal expansion makes it very resistant to thermal shock
  • Superior performance in environments of hot gasses and liquids including strong acids and bases, even at extremely high temperatures
