Description
Wear Resistance SI3N4 Silicon Nitride Ceramic ball
Advantages of Silicon Nitride Ceramic Ball:
1.Good hardness and wear resistance. This makes them highly resistant to wear and corrosion, even in harsh and abrasive environments.
2.Silicon nitride ceramic ball exhibit excellent thermal and electrical insulation properties.
3.Si3n4 ceramic ball bearing are non-magnetic and non-conductive, making them ideal for use in applications where magnetic interference or electrical conductivity could be a problem.
Silicon nitride ceramic is a man made compound synthesized through several different chemical reaction methods. Parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties.
