FAQs
What are fluid bearings and how do they work?
Fluid bearings are a type of bearing that uses a fluid, such as oil or gas, to support and lubricate moving parts. They work by creating a thin layer of fluid between the moving parts, which reduces friction and allows for smooth motion. This is achieved through the use of a specially designed bearing housing and a fluid circulation system.
