Engineering Custom Bearing Assemblies for Unique Medical Device Applications

Posted: May 1, 2025 1:11:02 PM

Medical technology is always rapidly changing, so precision and reliability are important factors. Custom-bearing assemblies are vital elements that guarantee medical device performance across surgical instruments and diagnostic equipment applications.

 The Critical Role of Custom Bearings in Medical Devices

Medical devices function under specific operating conditions, demanding parts that withstand multiple performance challenges.

  • Surgical instruments and robotic systems need ultra-small components for endoscopic applications while maintaining operational strength and functionality. Medical bearings also need miniaturization, creating specific challenges and innovative solutions.
  • Sterilization Compatibility: The bearings need to withstand multiple sterilization procedures by autoclaving while maintaining functionality.
  • Biocompatibility: Materials need to be chemically inert, so they do not react with human body tissues when they come into contact.
  • Low Noise and Vibration: The need for precision reaches its peak in diagnostic equipment because equipment noise can disrupt measurement results.

Custom-engineered bearings will solve these problems, allowing for devices functioning reliably and safely.

Our Approach to Custom Bearing Engineering

  • Collaborative Design: Our engineers work directly with clients to comprehend their application requirements, resulting in devices that perfectly match medical requirements.
  • Advanced Materials: We utilize several materials for bearing applications including:  52100 chrome steel providing strength and wear resistance, stainless steel 440C providing corrosion resistance and high hardness, stainless steel 316 providing superior corrosion resistance and biocompatibility and various glasses and plastics.
  • Precision Manufacturing: Our engineers use CNC Swiss machining to create medical device components with strict tolerances.
  • Quality Control: The production process includes testing procedures that follow ISO 9001 and ISO/TS 16949 standards to ensure consistent outcomes.
