Silicon Nitride Si3N4 Ceramic Roller:
Silicon Nitride (Si3N4) is 60% lighter than steel but strong enough to survive some of the most demanding applications in a variety of industries. This lightweight, high-strength ceramic material is used as an alternative to stainless steel, super alloys, tungsten carbides and first-generation ceramics such as Al2O3 and ZrO2. It offers excellent thermal shock resistance and high fracture toughness, compatibility with nonferrous metal melts, and improved structural reliability compared to other ceramic materials.
Product Features:
.Very low density
.High wear resistance and corrosion resistance
.High temperature resistance
.Good flexural strength and high fracture toughness
.Very good thermal shock resistance
.Dimensional stability and aging resistance
.Excellent sliding properties (tribology)
.Biocompatibility (for use in hygiene and the food and .beverage industry)
Typical Silicon Nitride Uses:
.Rotating bearing balls and rollers
.Cutting tools
.Engine moving parts - valves, turbocharger rotors
.Engine wear parts - cam followers, tappet shims
.Turbine blades, vanes, buckets
