Pivot Pin/Bearing

A pivot pin/bearing is a critical mechanical component in blade assemblies that facilitates controlled rotational motion around a fixed axis. It consists of a cylindrical pin that rotates within a bearing housing, providing low-friction movement while maintaining structural integrity under operational loads. This component ensures precise angular positioning, reduces wear through proper lubrication interfaces, and transfers mechanical forces from the blade to the machine frame.

The pivot pin rotates within its bearing housing to allow angular displacement of attached blades. Friction reduction is achieved through bearing surfaces (plain, roller, or ball bearings), while the pin's geometry maintains alignment and distributes radial/axial loads. Lubrication systems minimize wear, and tolerance controls ensure smooth operation without excessive play.
