Watches and Clocks: Sapphire is used in the watchmaking industry as jewel bearings. These are used as pivot points for the gears and balance wheel in mechanical watches. The extreme hardness of sapphire reduces friction and wear, contributing to the longevity and accuracy of timekeeping.
Pressure and Vacuum Gauges: Sapphire bearings are used in pressure and vacuum gauges where precise needle movement is required. The low friction and wear resistance of sapphire ensure accurate pressure readings.
Probes and Sensors: In various measurement probes and sensors, sapphire bearings are used to support and guide the moving parts. This is particularly important in precision measurement instruments where even the slightest friction or wear can affect the accuracy of readings.
Control Devices: Sapphire bearings can be employed in control knobs, sliders, and switches in control devices. The smooth and precise movement they provide contributes to accurate and reliable control over various functions.
Scientific Instruments: In high-precision scientific instruments, such as spectrometers, microscopes, and telescopes, sapphire bearings are used to facilitate smooth and stable movement of components. This ensures precise observations and measurements.
Aerospace and Defense: Sapphire bearings are used in navigation and control systems in aerospace and defense applications, where reliability, precision, and longevity are of utmost importance.
Industrial and Manufacturing Equipment: In industrial settings, sapphire bearings find applications in machinery and equipment where smooth, low-friction movement is required. They help reduce wear and improve efficiency.
Optical Devices: In various optical instruments and devices, sapphire bearings are used to support lenses, prisms, and other optical components. This ensures accurate optical alignment and stability.
Sapphire bearings are chosen for these applications because they offer exceptional mechanical and optical properties. Their hardness, smoothness, and resistance to wear make them ideal for reducing friction, maintaining accuracy, and increasing the lifespan of moving parts in various devices and instruments.
