Silicon Nitride Ceramic Ball G5 Precision Solid Bearing Balls
Dia 0.8mm-25.4mm
- This ceramic ball is a high grade silicon nitride ceramic ball with a very bright appearance and a high accuracy level for a wide range of uses, such as: full ceramic bearings, hybrid ceramic bearings, tools and gauges, valve seals, pumps, vans and more.
- Compared with steel ball, the main advantages of silicon nitride ball are :
- 01 59% lighter than steel balls, greatly reducing the bearing high-speed and accelerated operation of the centrifugal force on the groove, crushing and wear;
- 02 The modulus of elasticity is 44% larger than steel, which means that the amount of deformation in the force is greatly reduced than steel balls;
- 03 Higher hardness than steel, HRC reaches 78;
- 04 The coefficient of friction is small;
- 05 Coefficient of thermal expansion is 1/4 of steel, can withstand drastic changes in temperature;
- 06 Easy to obtain a high surface finish, Ra can reach 4 to 6 nanometers;
- 07 High temperature resistance: silicon nitride ceramic ball at a high temperature of 1050 ° C still has a high strength, hardness;
- 08 Never rust, can work in oil-free lubrication conditions;
- 09 More resistant to chemical corrosion than steel;
- 10 No metal pollution;
- 11 Non-magnetic;
- 12 Electrically insulated.
- 13 No adhesive wear;
- The combination of these excellent properties makes silicon nitride the first choice for high-performance bearing rolling element materials.
- According to your choose.
