Description

Silicon Nitride Balls

Silicon Nitride Balls are specified for use in such high-technology industries such as full ceramics bearing, hybrid bearings, aerospace and defense, they are featured in 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, 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.
  • Ortech balls manufacturing capability ranges in size from 0.5mm to 63.50mm.
  • We offer Silicon Nitride balls conforms to ASTM Specification F2094; Class I and Class II materials .
