● Saves internal equipment space while ensuring operational stability
● Eliminates oil contamination risk at the source
● Meets medical environment cleanliness requirements
● Low friction coefficient reduces component wear significantly
● Maintenance-free operation for extended periods
● Dense and stable surface coating
● Resistant to alcohol and iodophor wiping
● Withstands high-temperature steam sterilization (134°C, 3 cycles minimum)
● No coating peeling or substrate rusting after repeated disinfection
● Key mating parts achieve IT4-IT5 tolerance levels
● Micron-level accuracy for radial runout and coaxiality
● Low noise operation (≤30 dB) with minimal vibration
● Compatible with precise operation requirements of medical equipment
Our Medical Device Motor Shafts are designed to meet the precision, sterility, low-noise, and maintenance-free requirements of medical scenarios. They serve as core transmission components in various high-end medical equipment.
