Compared with steel ball, Si3N4 ball has following advantages:
Diameter specification: Ф0.4mm~Ф140mm
Available supply level: G5 ~ G100.
stable quality and high consistency with ASTM F2094-03a standard.
Si3N4 ball can be used in all bearings with special requirement: high speed bearing, high precision bearing; vacuum bearing; high/low temperature bearing, non-magnetic bearing, high precision ball screw; Si3N4 ball can also be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump. Si3N4 ball can also be used in linear slider for high temperature and corrosion resistance
Si3N4 ball is generally assembled in bearing for application in high-tech industry such as aerospace, national defense, chemical industry, metallurgical, medical, food, oil plant, electronic etc.
Remarks: 1) black color as standard, gray color could be supplied upon customer requirement. 2) Plenty of stock. 3) Non-standard size and different gauge could be supplied. 4) GPS and HIP Si3N4 balls are available.
