Abstract

Sapphire bearings are precision components made from synthetic sapphire, a form of corundum known for its exceptional hardness and durability. These bearings consist of metal spindles rotating within jewel-lined pivot holes, typically shaped like a torus and slightly larger than the shaft diameter. The use of synthetic sapphire ensures high dimensional accuracy, low friction, and excellent temperature stability, making them ideal for applications requiring long life expectancy and reliability. Commonly utilized in mechanical watches, sensitive measuring instruments, and various industrial applications, sapphire bearings offer superior performance compared to traditional materials, maintaining smooth operation over extended periods without lubrication.
