High Strength | Wear Resistant | Mechanical Seal Solution
Our Silicon Nitride Ceramic Seal Ring (Si3N4) is designed for mechanical seal and pump applications requiring excellent wear resistance, high strength, and long service life.
Compared with traditional carbon or alumina seals, silicon nitride provides lower friction, higher hardness, and superior thermal stability.
Widely used in industrial pumps, chemical equipment, high-speed rotating shafts, and harsh working environments.
✅ Excellent Wear Resistance
High hardness and low friction coefficient reduce wear and extend service life.
✅ High Mechanical Strength
Suitable for high-speed rotation and high-load sealing conditions.
✅ High Temperature Resistance
Stable performance under elevated temperatures without deformation.
✅ Chemical & Corrosion Resistance
Suitable for aggressive media such as acids, alkalis, and solvents.
✅ Precision Machining
CNC machined and finely ground for tight tolerance and smooth sealing surface.
✅ Custom Design Available
OEM & ODM supported based on drawings or samples.
