Ceramic Balls
Silicon nitride ceramic balls and ceramic roller
Silicon nitride ceramic balls and ceramic roller have the performance of high strength, high hardness, wear resistance, high rigidity, corrosion resistance, high temperature resistance, electrical insulation, non-magnetic, low gravity which many metal materials do not have. They are the preferred material to be made of high-temperature structural materials and ceramic bearings.
Its features are as follows:
1, Strong corrosion resistance, acid, alkali. They can be used in seawater.
2, High temperature. The strength of silicon oxide ceramic balls at 1100 ℃ is almost unchanged.
3, They can be used in the non-magnetic, electrical insulation and magnetic field.
4, The performance of a density of 3.26g / cm3, light weight and about 60% lighter than steel ball greatly reduces the centrifugal force of the high speed rotation of the bearing channel and reduces wear and tear.
5, High rigidity, high strength, high hardness bearing steel is than doubled. High modulus of elasticity is about 1/2.
6, The coefficient of linear expansion 3.2X10-6 / K, almost 1/4 of bearing steel, is able to withstand sudden temperature change.
7, Self-lubricating silicon nitride ceramic ball bearings can solve the pollution caused by lubricating medium and add the inconvenience, can be used in vacuum and high temperature.
8, chemical resistance, high mechanical strength, low on maturity.
Production specifications: 1.588-101.6mm Precision: G5-G200
Application: High-precision ceramic bearings, high temperature bearings, vacuum bearing, non-magnetic bearings, chemical pumps, heat pumps, ceramic valves, measuring ball.
