Silicon Nitride Ceramic Ball
Material: Zirconia, Alumina, Si3N4
Size: 0.1mm - 50mm
Grade: G3- G20mm
Color: Black, White
Shanghai Metal Corporation is a professional manufacturer and supplier of Silicon Nitride Ceramic Ball with high quality and reasonable price.
Silicon Nitride Ceramic Grinding Ball is made of the hot isostatic pressing and sintering furnace and has the properties including high strength,high wear resistance,high temperature,corrosion,acid and alkali resistant,long-term using in the sea,good electrical insulating ect.
If you want to know more about price of Silicon Nitride Ceramic Ball products, please feel free to contact us, we will reply you within 24 hours.
The ring and roller of our ceramic bearing adopts full ceramic materials including zirconia (ZrO2), silicon nitride (SisN4), silicon carbide. The cageare made of plastic material: PTFE、PEEK、PA66、SUS304、SUS316, which extends the application of ceramic bearing, high temperature resistant,corrosion resistant, anti magnetic bearings, bearing, electrical insulation bearing, etc.
High temperature resistant bearing: The material itself has resistance to high temperature 1200 ℃, and good self-lubrication, tem- perature between 100℃ to 800℃ should not produce temperature difference caused by the expansion. Can be used in the kiln, mold- ing, plastic steel and high temperature equipment:
Corrosion resistant bearina: As the material itself has the property of corrosion resistanceit can be used in strong acid, strong alkali inorganic salt, organic salt and sea water and other fields suchas:Semiconductor equipmentLCD equipment,Food machinery,Electro- plating equipmentChemical equipment,Textile machineryMedical machinery, shipbuilding and so on.
Magnetically bearings: As it does not absorb dust,which reduce the early spalling of bearing, large noise, etc. lt can be applied in the demagnetization equipment, precision instruments and other fields. Electric insulation bearing: As it has high electric resistance,which can avoid arc damage to bearing .lt can be applied in power system requiring insulation.
Vacuum bearing: As ceramic material has unique oilless self-lubrication propertyit can be applied in ultra high vacuum environment. It can solve the lubrication problem that can not overcome by ordinary bearings
