Bearings are a common component for numerous types of machinery, regularly implemented within assemblies for the means of minimizing the amount of friction generated between two moving surfaces. There are many types of bearings that one may use for friction reduction, and each may provide its own unique abilities to benefit certain applications. Jewel bearings in particular are a form of plain bearing that features a hard gem for their design. Due to their construction and design, such aviation bearing types are well suited for surviving some of the most extreme environments, all while remaining accurate and reliable. In this blog, we will provide a brief overview of the jewel bearing, allowing you to better understand their functionality, advantages, and common uses.
