Product Description

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 *0% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration. Superior Surface Finish, Ra 0.1 **0.*5 micro inches may extend L**0 life to as much as *0 times that of steel bearings. High Temperature Hardness is twice that of steel. These all-ceramic balls retain their strength and hardness up to ***0 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 Hoover's exacting manufacturing standards regarding sphericity, diameter tolerance, and surface finish, make Hoover's silicon nitride balls ideal for high performance ball bearings.
