Rolamentos de cerâmica de nitreto de silício

Características de Design

Silicon nitride ceramic bearing rollers, also known as high-strength wear-resistant ceramic bearing cylinders, demonstrate the excellent properties of silicon nitride as a high-performance material, suitable for applications requiring extreme durability and performance:

Excellent Mechanical Strength and Wear Resistance

Silicon nitride boasts a Vickers hardness up to 1500 HV and a flexural strength of 600 MPa, providing outstanding wear resistance and fracture toughness under high load conditions.

Superior Corrosion Resistance and Heat Resistance

These bearing rollers can withstand temperatures up to 1200°C, making them suitable for high-temperature environments, while their chemical stability ensures longevity in corrosive environments.

Low Density and High Performance

With a density of only 3.2 g/cm³, silicon nitride offers reduced weight compared to traditional metal materials, contributing to improved operational efficiency and speed of mechanical equipment.
