Ruby Tubes and Ruby Bearings are specialized components that make use of the unique properties of synthetic ruby (a form of corundum, or aluminum oxide, that is chemically treated to have the desired hardness and strength). These components are widely used in industries that require precision, durability, and resistance to wear, especially in high-performance environments such as watches, medical devices, and aerospace.
