Industrial Silicon Nitride Ceramic Ring Sleeve: High-Precision Bearing Race & Seal Ring

Product Introduction

This product is an industrial ceramic ring sleeve manufactured from high-performance silicon nitride (Si3N4), specifically designed for precision machinery and demanding operating conditions. It features a dark gray color with a uniform, fine matte texture, reflecting the material's high density and superior quality. Structurally, it adopts a standard ring design with precise inner and outer diameters, flat end faces without chamfers, and uniform wall thickness, presenting a clean cylindrical ring profile. The high machining accuracy ensures smooth inner and outer walls free of defects, guaranteeing easy installation and stable operation. This silicon nitride ceramic sleeve combines excellent material properties with a precise structure, making it an ideal choice for enhancing equipment reliability and service life.

Core Advantages

• Exceptional Wear Resistance: High hardness and extremely low coefficient of friction significantly reduce wear on mating components.

• Excellent High-Temperature Resistance: Maintains stable performance in high-temperature environments up to 1200°C without softening or deformation.

• Outstanding Corrosion Resistance: Resists corrosion from most acids and alkalis, suitable for harsh environments like chemical processing.

• High Strength and Rigidity: Excellent flexural strength and fracture toughness, capable of withstanding high-load conditions.

• Good Insulation Properties: An excellent electrical insulating material, suitable for applications requiring electrical insulation.

• Lightweight Design: Lower density than metal materials, contributing to equipment weight reduction.

Typical Applications

• Precision machine tool spindle bearing races

• Mechanical seal rings for chemical pumps

• Positioning sleeves in automation equipment

• Structural components in semiconductor equipment

• Insulating parts for high-temperature equipment
