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 a non-porous, non-magentic, non corrosive, and lighter than steel material. Silicone nitride balls are harder than steel allowing them to withstand the most rigorous environments. Ceramic balls are almost friction-less because they are non-porous which gives them the ability to spin faster than steel balls.
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, 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 as hard than steel. These all-ceramic balls retain their strength and hardness up to 1800 degrees F.
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.
The aerospace industry, machine tools, measurement instruments, pumps and compressors as well as many other industries that require high precision high performance balls.
