Silicon Nitride Ceramic Rings

Silicon Nitride Ceramic Ringsmerits

The greatest advantage of silicon nitride ceramic rings lies first and foremost in their high strength and excellent compressive stability. In axial compression, radial support and high-speed rotation systems, ring components are often subjected to large surface pressures and localized loads on a continuous basis. Ordinary metal rings are prone to wear, deformation and even oxidation at high temperatures or under long-term friction, whereas silicon nitride, with its extremely high flexural strength and high hardness, can maintain long-term dimensional stability of the inner and outer diameters and planar integrity.
