Small Bearings for Surgical Tools: Precision Solutions for Medical Equipment
Introduction
Small bearings for surgical tools form the critical pivot points in modern medical devices, directly impacting instrument precision in procedures ranging from arthroscopy to dental surgery. Global medical device manufacturers face mounting pressure to source components that simultaneously meet strict sterilization requirements, micro-scale precision tolerances, and international compliance standards.
Technical Specifications & Standards
Medical-grade bearings must comply with:
- ISO 13485:2016 (Medical devices quality management)
- ASTM F2097 (Cleanliness standards)
- Corrosion resistance: Minimum 500hrs salt spray test
- Operating temperature: -70°C to 300°C
Material Comparison Table
| Material | Advantages | Disadvantages |
|---|---|---|
| 440C Stainless | High hardness (58-62 HRC) | Limited chemical resistance |
| Ceramic Hybrid | Zero magnetic interference | 30% higher cost |
