Silicon Nitride Balls are Engineered for High Precision Applications

Specified for use in such high-technology industries such as hybrid bearings, aerospace and defense; Silicon Nitride ceramic balls feature these advanced characteristics:

• 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 F.

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.

These outstanding properties, together with Global Precision's exacting manufacturing standards regarding sphericity, diameter tolerance, and surface finish, make Global Precision's silicon nitride balls ideal for high performance ball bearings.
