Silicon Nitride Balls from Global Precision

Global Precision is proud to offer a large selection of sizes and grades of this product in both standard and metric.

Ceramic balls are particularly well suited for use in extremely harsh environments where high temperatures, corrosive and erosive substances are present.

Silicon Nitride Balls

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 0.17-0.25 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.
