Product Description
Silicon nitride ceramic balls are excellent in strength, toughness and performance. They come in several grades, types and sizes, as per the need of applications. These balls are practical in bearings, machine tools, and other industrial. They are chemical composite of silicon and nitrogen. As a hard ceramic, these products feature high strength, broad temperature range, low coefficient of thermal expansion, high fracture toughness, and moderate thermal conductivity. Also, the silicon nitride ceramic balls offer excellent thermal shock resistance, superior wear resistance, and withstand high structural loads.

Classification:

  • Grinding Ball:the size is 1.5-40MM

Features:

  • Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions.
  • Lightweight Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration.
  • Superior Surface Finish, Ra 0.1 7-0.25 micro inches may extend L-10 life to as much as 10 times that of steel bearings.
  • .High Temperature Hardness is twice that of steel. These all-ceramic balls retain their strength and hardness up to 1800 degrees
  • Silicon Nitride is further characterized by its low density of 3.2 g/cc, high flexural strength of 1.0 GPa, and fracture toughness of 6 MPa/M2.
