Silicon Nitride Ceramic Bearing Balls

Si3N4 ceramic balls is a precision ceramic sintered at high temperature in a non-oxidizing atmosphere,with high strength, high wear resistance, high temperature resistance, high corrosion resistance , can be used in seawater for a long time, and have good electrical and magnetic insulation properties. At 1000℃, the strength and hardness remain almost unchanged. Its density is 3.23g/cm³, which is almost 1/3 of the weight of bearing steel. The centrifugal force is small during rotation, which can realize high-speed operation. It also has self-lubricating properties and can be used in highly polluted environments without lubricating media. It has become the preferred ball for ceramic bearings.

Features:

Lightweight, wear-resistant, long life, high strength, self-lubricating, electrical insulation, etc., it demonstrates reliability and safety in application environments that require high speed, maintenance-free, and anti-electrical corrosion.

Application:

High-speed/ultra-high-speed bearings, machine tool spindles, electric vehicles, wind power generation, motors, X-ray CT, aerospace, semiconductor vacuum pumps; can also be used as valve balls and measuring balls in chemical pumps, high-temperature pumps, and metering pumps.
