Silicon nitride ceramic roller guides have superior hardness and self-moistening properties, so they are very wear-resistant. 

In addition, silicon nitride ceramics do not react with other inorganic acids except hydrofluoric acid and have strong corrosion resistance. 

Moreover, it has excellent thermal shock resistance, and will not break when heated to 1000 ° C in the air and then cooled rapidly.

Application:

⭐️Rotating ball and roller bearings.

⭐️Cutting tool.

⭐️Engine components: valve, rocker arm pad, sealing surface.

⭐️Induction heating coil bracket.

⭐️Turbine blade, wheel blade, bucket.

⭐️Welding and brazing fixtures.

⭐️Heating element assembly.

⭐️Crucible.
