Features:

1.Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions.

2.Lightweight Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration.

3.Superior Surface Finish, Ra 0.1 7-0.25 micro inches may extend L-10 life to as much as 10 times that of steel bearings.

4.High Temperature Hardness is twice that of steel. these all-ceramic balls retain their strength and hardness up to 1800 degrees F.

5.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.
