Sapphire Bearings

Ruby bearings, also known as ruby jewel bearings, are precision components used in various instruments, meters, and control devices. These bearings are made from synthetic rubies, which are a type of corundum, a mineral composed of aluminum oxide (Al2O3). Synthetic rubies are valued for their exceptional hardness, smoothness, and resistance to wear, making them ideal for applications where low-friction movement, high precision, and durability are critical. Here’s how ruby bearings are used in instruments, meters, and control devices:


Automotive Instruments: Ruby bearings can be found in automotive instruments like speedometers, tachometers, and fuel gauges, ensuring precise needle movement.

Aerospace and Defense: Ruby bearings are used in navigation and control systems in aerospace and defense applications, where reliability, precision, and durability are essential.

Industrial Equipment: In industrial machinery and equipment, ruby bearings are utilized where precise and low-friction movement is required. They contribute to reducing wear and improving operational efficiency.

Measurement and Sensing Devices: Ruby bearings can be used in various measurement probes, sensors, and transducers to support and guide moving parts. Their low friction and wear resistance are essential for precise measurements.

Ruby bearings are chosen for these applications due to their remarkable mechanical and material properties. Their extreme hardness and smooth surface reduce friction and wear, contributing to the longevity and precision of moving components in various instruments and control devices.

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.
