Description

High Precision Silicon Nitride Ceramic Ball for Ball Bearing

Description:

Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance and high strength. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

ClassⅠ Liquid oxygen pump,Active shaft bearing The key parts of aerospace equipment
ClassⅡ Vaccum equipment,high speed instrument,mechanical devices,high performance and the most advanced contacting spherical propeller Motor,medium-low precision star bearing Testing bearing ball,separating bearing ball
ClassⅢ Sport,entertrainment,food processing Mechanical devices


Advantages:

1. High Strength over a wide temperature range.
2. High Fracture toughness.
3. High Hardness.
4. Outstanding Wear Resistance ,both impingement and frictional modes.
5. Good Thermal Shock Resistance.

Application:

Most ceramic balls are mounted in the bearing (high-speed bearing, high precision bearing, vacuum bearing, high/low-temperature bearing, nonmagnetic bearing, high precision ball screws) for the high technology industry, such as aerospace and national defense and etc. The ceramic balls can also be used for chemistry, metallurgy, medical treatment, food industry, oilfield, electronic engineering and etc.
