for use in such high-technology industries such as hybrid
bearings, aerospace and defense; Silicon Nitride ceramic balls
feature these advanced characteristics:
corrosion resistance withstands attack from harsh chemicals and
demanding environmental conditions.
Silicon Nitride weighs 60% less than steel which reduces
centrifugal force, skidding and wear under high speed and
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.
Temperature Hardness is twice that of steel. These all-ceramic
balls retain their strength and hardness up to 1800 degrees F.
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
outstanding properties, together with Hoover's exacting
manufacturing standards regarding sphericity, diameter
tolerance, and surface finish, make Hoover's silicon nitride
balls ideal for high performance ball bearings.
