Challenge
A leading medical equipment manufacturer needed its ventilators to maintain extremely tight tolerances over long service lives. Aging components in the check valves, critical for ensuring one-way oxygen flow into patients’ lungs, were shortening product lifespan and increasing maintenance costs. The company required a cost-effective way to extend service life without compromising performance or safety.
Solution
Boca Bearings’ in-house engineering team collaborated with the customer’s product development group to redesign the check valve ball using aluminum oxide (Al₂O₃) ceramic. This material:
- Met the ventilator’s extremely tight dimensional and performance tolerances
- Provided superior corrosion resistance, directly addressing a key failure mode
Boca Bearings’ purchasing team, with nearly 40 years of experience, then leveraged its vendor network to secure a reliable and high-quality supply of these ceramic balls, consistently meeting the strict specifications of medical devices.
Results
- Service life doubled: The upgraded Al₂O₃ ceramic ball effectively doubled the lifespan of the ventilator check valves.
- Greater reliability: Improved durability reduced wear-related failures in mission-critical life-support devices.
- Critical impact: The upgrade was implemented as global ventilator demand surged during the COVID-19 pandemic, helping the manufacturer support more patients in need.
