Four Industrial Application Cases
1. Mining & Mineral Processing
- Problem: Metal sleeve bearings failed every 3 months in slurry pumps due to abrasive quartz particles.
- Solution: Installed low-clearance Alumina Ceramic Sleeve Bearings.
- Result: Extended service life and reduced downtime.
2. Chemical Processing Pumps
- Challenge: HF acid corroded stainless steel liners in 6 weeks.
- Upgrade: Zirconia Ceramic Liners with Isostatic Pressing treatment.
- Outcome: High corrosion resistance greatly increases the service life.
3. Food/Beverage Conveyor Systems
- Requirement: USDA-compliant, bacteria-resistant bearing surfaces.
- Implementation: Ultra-smooth 99.7% alumina ceramic bushings.
- Benefit: Achieve CIP/SIP cleaning and effectively reduce product contamination.
4. Semiconductor Wafer Handling
- Precision Need: ±5μm positioning accuracy in vacuum robots.
- Solution: Precision-Ground Zirconia Sleeves with low runout tolerance.
- Yield impact: Significantly reduced particle generation vs. PEEK components.
