hydrodynamic bearings

Hydrodynamic bearings are mechanical components that support rotating parts, like shafts, by creating a thin film of lubricant—usually oil—that separates moving surfaces. When the shaft rotates, it generates a pressure in the lubricant film due to the fluid’s movement, which lifts and supports the shaft, reducing contact and friction. This oil film acts like a cushion, allowing smooth rotation with minimal wear. Hydrodynamic bearings are used in engines, turbines, and heavy machinery to improve performance and longevity by efficiently handling loads and reducing friction-related damage.
