Engineered for high precision applications, silicon nitride ceramic balls deliver unsurpassed performance in critical components such as hybrid bearings.
Specified for use in such high-technology industries as aerospace and defense, high-spec ceramic balls feature these advanced characteristics:
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 maximum micro inches ' may extend L-10 life to as much as 100 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 manufacturing standards regarding sphericity, diameter tolerance, and surface finish, make silicon nitride balls ideal for high performance ball bearings.
