Specification of Premium Si3n4 Silicon Nitride Ceramic Bearings for Global Trade

Premium Si3N4 Silicon Nitride Ceramic Bearings deliver top performance for demanding global applications. They are built for extreme conditions. These bearings use high-purity silicon nitride powder. The purity level exceeds 99%. This ensures consistent material quality.

The material density is very high. It typically measures around 3.25 g/cm³. This density contributes directly to exceptional strength. The bearings resist breaking under heavy loads. Their hardness is also outstanding. It reaches approximately 1500 HV. This hardness makes them highly resistant to wear. Abrasion damage is significantly reduced.

These ceramic bearings handle intense heat extremely well. Their maximum operating temperature is 1200°C. They perform reliably where steel bearings would fail. Thermal shock resistance is another key feature. Sudden temperature changes won’t crack them. This is vital in many industrial processes.

Corrosion resistance is a major benefit. Harsh chemicals, salt water, and acids do not damage them. They are perfect for marine, chemical, and food processing equipment. Electrical insulation properties are also important. They prevent electrical arcing damage. This is critical in electric motors and generators.

The bearings are much lighter than steel. This reduces friction and energy loss. Rotating machinery runs smoother and cooler. Fuel efficiency improves in vehicles. Machine lifespan often increases. Maintenance costs usually decrease. Non-magnetic properties are essential for specific sectors. MRI machines and semiconductor tools require this.

These bearings meet strict global standards. Dimensions follow ISO or ABEC precision grades. Radial play is controlled precisely. Surface finish is exceptionally smooth. This minimizes friction and vibration. Cage options include reinforced polymers or special metals. Each option suits different speed and load needs.

Si3N4 bearings offer a unique combination of properties. They provide long life and reliability in tough environments. Global industries rely on their performance. They are a smart investment for critical machinery.
