Your Most Reliable Supplier Since Year 1980 With Steady Quality:
Reactive Sintered Silicon Nitride Si3N4 Sealing Ring And Bearing For High Thermal Environment And Good Corrosion Resistant!Produced By Isostatic Pressing Hi-Tech To Assure Good Quality! For Industrial Mechanical Purpose!
Size range:Bore diameter: 3~150mm; Length: 5~300mm And Customized Dimensions
Silicon nitride bearing are used for metal processing applications including drawing, guiding, extrusion, etc in wire and cable industry. Metals to be processed could be brass, copper, bronze, aluminum, titanium, steel, and other various metals. Shapes could be rod, tube, wire, and other complex shapes.
Advantages:
1. Longer service life of bearing. Service life of silicon nitride bearing is about 9 times and 2~3 times longer than that of metal and tungsten carbide bearing, respectively.
2. Higher working temperature. Silicon nitride bearing could be used at temperature up to 1000°C. While generally, steel bearing can only be used below 300°C
3. Better surface roughness quality of the metal works is achieved
4. Pick-up of the metal works is eliminated
5. Scrap of metal works is reduced
6. Consistency and reliability of metal works is in creased
7. Post-processing of metal works is reduced
8. Productivity is increased
