Bearings in medical devices play a crucial role in ensuring smooth movement, reducing friction, and enhancing precision. They are commonly used in equipment such as surgical robots, diagnostic machines, and prosthetics. Bearings allow for accurate motion control in devices like infusion pumps and dental drills, improving both the functionality and longevity of the equipment. Their ability to withstand stress, maintain alignment, and reduce wear and tear is essential for the reliability and performance of medical devices in critical healthcare applications.
