1MM-20MM Silicon Nitride Balls Si3N4 Balls
Product Description————————
Silicon Nitride Ceramic Ball is the most ideal bearing ball for
bearing applications, due to the excellent properties of silicon
nitride ceramics, it has many irreplaceable advantages comparing to
traditional steel materials, such as: high mechanical strength, low
wear loss, good self-lubrication, low density, high corrosion
resistance, good electrical insulation etc.
Therefore, Silicon Nitride Balls are mostly used for some harsh
working conditions: high speed/super speed bearings, high precision
bearings, bearings in vacuum, high/low temperature bearings.Moreover, Silicon Nitride Ceramic Balls can also used as valve ball
or measurement balls in chemical pumps/high temperature
pumps/metdering pumps.
Features————————
1. Exceptional Wear Resistance: silicon nitride ceramic beads
exhibit outstanding resistance to wear, ensuring longevity and
durability in abrasive environments.
2. Precision Sizing: With a consistent diameter range of 0.8-1.0mm,
these Si3N4 ceramic balls offer precise sizing, crucial for
applications requiring uniformity and accuracy.
3. High Hardness: Engineered with high hardness properties, our
silicon nitride ceramic beads provide excellent resistance to
abrasion, making them suitable for demanding grinding and milling
processes.
4. Corrosion Resistance: These ceramic beads feature superior
corrosion resistance, ensuring reliable performance even in harsh
chemical environments, enhancing their suitability for diverse
industrial applications.
5. Temperature Stability: Designed to withstand high temperatures,
our Si3N4 ceramic balls maintain their structural integrity and
performance under extreme heat conditions, ensuring consistent
results in thermal processing applications.
6. Versatile Applications: From grinding and milling to polishing
and surface finishing, our silicon nitride ceramic beads find
versatile applications across various industries, including
electronics, ceramics, and advanced materials processing.
