Bearing/Bushing

A bearing or bushing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. In blade/louver assemblies, these components support rotating shafts or pivoting mechanisms, allowing smooth operation while handling radial and axial loads. They maintain precise alignment, absorb vibrations, and extend equipment lifespan by minimizing wear.

Bearings/bushings operate on the principle of separating moving surfaces with a lubricated interface or rolling elements. They convert sliding friction into lower rolling friction (in ball/roller bearings) or utilize hydrodynamic lubrication (in bushings) to support loads while allowing controlled motion with minimal energy loss.
