Client Requirement
A pharmaceutical equipment manufacturer required a gear reducer for robotic arms operating in a Class 100 cleanroom environment used for vial sorting, packaging, and labeling. The gearbox needed to be fully sealed, low-noise, maintenance-free, and resistant to aggressive sanitization agents used in GMP-certified facilities. The focus was on high reliability and long-term precision.
Technical Specifications
- Protection: IP67-rated housing
- Cleanroom compliance: ISO 14644 Class 5 compatible
- Surface: Polished 316 stainless steel, Ra ≤ 0.6 μm
- Lubrication: H1 food/pharma-grade grease
- Output torque: 30 Nm nominal, 60 Nm peak
- Temperature resistance: 0°C to 60°C, non-condensing
- Magnetic encoder compatibility for position feedback
- Lifetime: >20,000 hours under high-frequency wash cycles
Our Solution
We engineered a compact, low-backlash planetary gearbox designed specifically for pharmaceutical cleanroom use:
- Hermetically sealed with double O-ring and internal pressure stabilization
- Anti-microbial coating and smooth surfaces to eliminate contamination risk
- Grease-lubricated for life, with zero particle shedding
- Support for direct coupling with stepper/servo motors
- Fully compliant with GMP and FDA material standards
Results
- Successfully passed cleanroom particle emission tests (ISO 14644-1)
- Operates with ±0.02° positioning accuracy
- Zero lubricant leakage over 18 months of continuous use
- Reduced equipment downtime and maintenance costs by 40%
