Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitride is nonporous, nonmagnetic, non corrosive, lighter than steel and, in ball form, is harder than steel.
Ceramic balls can also provide high stiffness, low thermal expansion, light weight, increased corrosion resistance, and electrical resistance. Boca Bearings stocks a wide assortment of Silicon Nitride Ceramic Balls, Alumina Oxide Ceramic Balls and Zirconia Ceramic Balls. Can .

Silicon Nitride (Ceramic Ball) Silicon Nitride (Si 3 N 4) ceramic has become the standard ceramic ball material for hybrid Ball Bearings. This material is very hard, over 2000 Knoop, and very wear resistant. The weight of silicon nitride balls is only 40% of steel at grams per cm³ (cubic centimeter) .
The most common use for silicon nitride balls is in bearings. Silicon nitride bearing balls have a coefficient of thermal expansion just 25% if most steel balls, so there is less friction generated in the bearing as heat increases. The low thermal conductivity of silicon nitride balls reduces the amount of heat absorbed, thus reducing cooling ...

Ceramic balls are formed from a modern material suitable for applications where high speeds and extreme temperatures are factors. The need for extended life and minimal lubrication make this material ideal for demanding applications. Ceramic is not porous, magnetic, or .
Silicon Nitride is further characterized by its low density of g/cc, high flexural strength of 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.
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.
