Silicon Nitride Balls Specified for use in such high-technology industries such as full ceramics bearing, 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 60% less than steel which reduces centrifugal force, skidding and 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 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.
Ortech Silicon Nitride ball manufacturing capability ranges in size from 0.5mm to 63.50mm.
