Silicon ceramic ball is the precision ceramics sintering in the high temperature oxidation

atmosphere , It has the advantage with high strength, high wear resistance, high temperature

resistance, corrosion resistance, acid, alkali, which can be used in water medium, and has the

good performance of magnetic insulation .

At 800 ℃, the strength and hardness will not chage, its density is 3.20 g/cm3,its wight is almost

1/3 of the steel bearing.Its rotating centrifugal force small so it can realize high-speed operation.

It also have self lubrication, it can be used to no lubrication medium environment.It Become the

best choice of ball bearing.

Key Silicon Nitride (Si3N4) Characteristics:

? Good thermal shock resistance
? Creep resistance
? Low density
? High fracture toughness
? High hardness and wear resistance 
? Electrical resistivity

 Other Type of silicon nitride ceramic include:shaft,pipe,tube,sleeve,bushing,nozzle,bar,tile,plate,disc,substrate,crucible,ring ect.

Typical Silicon Nitride Uses:

? Rotating bearing balls and rollers

? Cutting tools

? Engine moving parts — valves, turbocharger rotors

? Engine wear parts — cam followers, tappet shims

? Turbine blades, vanes, buckets

? Metal tube forming rolls and dies

? Precision shafts and axles in high wear environments

? Weld positioners
