Ultra-Wear-Resistant Tungsten Carbide Cylinder with Silicon Nitride Shaft Assembly

Product Overview

The high-performance assembly combining a tungsten carbide cylinder with a silicon nitride shaft is specifically engineered for extreme operating conditions. This combination significantly outperforms traditional metal materials in wear resistance, corrosion resistance, and high-temperature stability, extending service life by 3 to 5 times while dramatically reducing maintenance frequency and costs.

Tungsten Carbide Manufacturing Process

We employ advanced powder metallurgy techniques to manufacture tungsten carbide cylinders:

1. Material formulation: High-purity tungsten carbide powder is precisely mixed with cobalt binder in specific ratios

2. Forming process: Isostatic pressing technology ensures uniform material density with forming accuracy of ±0.01mm

3. Sintering: Vacuum sintering at 1400-1600℃ creates a dense microstructure

4. Precision machining: Diamond grinding tools achieve surface roughness below Ra0.05μm

5. Quality inspection: Multiple testing procedures including ultrasonic flaw detection and hardness testing

Core Technical Advantages

• Material properties: Tungsten carbide hardness exceeds HRA 90, while silicon nitride provides self-lubrication with friction coefficient as low as 0.1

• Precision manufacturing: Mirror-polished cylinder interior (surface roughness Ra≤0.05μm), shaft machining tolerance controlled within ±0.001mm

• Customization: Available in diameters from 10-500mm with various surface coating options Key Benefits Summary

• Extended service life: 5 times more durable than traditional stainless steel components

• Energy efficiency: Reduces friction losses by 60%

• Maintenance-free design: Corrosion-resistant materials require no additional lubrication

• Easy installation: Standardized interface design compliant with ISO/DIN specifications
